NRAM - The New Hard Drive Technology That Will Revolutionize the Computer World

By Bob Randooke

Have you guys been noticing how computer hard drive prices have been going down very much lately. Though there are quite a few factors that are the causes for this such as the current recession that we are and the technology keeps improving but there are also other technologies on the horizon that could revolutionize our drive technology to the point that current hard drives available today could become obsolete.

Here I will talk about one major technology that could revolutionize the computer industry just as much or even more than the Internet revolution did during the late 1990s. The new hard drive technology that I am talking about is called NRAM. NRAM or nonvolatile random access memory is a hard drive technology that is based on mechanical position of carbon nano tubes that are deposited on small substrates, and because the NRAM technology is based on small size nanotubes this will allow you to carry a huge amount of memory in a very small space. The current company that is developing the NRAM technology is called Nantero.

Now, besides the difference in size between the nano tubes and what DRAM (DRAM has a minimum size limit that it can be built to) currently has to offer there is also an added benefit that NRAM has over DRAM in that DRAM requires a certain amount of power to refresh it, while NRAM does not require any power source at all to refresh its memory even after the power source that is required to refresh it is removed.

Another energy-saving benefits to NRAM as opposed to DRAM is that the power that is needed to write to the device used is much lower than it would be for DRAM. The RAM has to build up a charge on its plates to get powered up. Most people will not notice this but this is a tremendous energy saving benefits that will cut down on the amount of electricity needed to not only power up our computers but to keep them turned off.

NRAM in theory can operate at a much better efficiency than DRAM and it will be much less dense than DRAM and eventually much less expensive. Imagine having an instant on computer where you just push the on button and your computer is powered up right there on the spot without waiting 10 to 30 seconds or even a minute for this to happen.

Imagine being able to store hundreds of terabytes of information on your hard drive. The possibilities to this technology and to the amount of memory that your computer can store in its hard drives is almost limitless. The low energy needed to power up and to keep the NRAM device going is even much less than flash memory and this is another area that the NRAM technology can enter into. Imagine being able to take an MP3 device as small as your hand with you anyplace you go that has a 3 TB storage capacity. The marketing capacity for this technology is in the hundreds of billions of dollars and could reach into the trillions of dollars later on. NRAM is a computer hard drive technology revolution that is waiting to happen. Now whether it happens in a few years or in five years this will be the most exciting new technology in the computer hard drive sector that has ever come about. Nantero has attracted all the big names in the computing industry and technology including HP, LSI and ON semiconductor. All of these major technology guys are either looking into experimenting with NRAM in their labs are actually trying to produce the chips themselves. It seems to me now that Nantero will probably license the technology out to big companies like these.

I can't wait for this technology to hit the market as I think it will revolutionize the way we store computer memory in a way that we are not currently used to doing. The energy savings of this hard drive technology couldn't come at a better time in the world that is energy starved World.

Author writes about new technologies in the Computer Desktops industry to show how desktop computers will change in the upcoming years.

5 Ways to Take Care of Your System After Your Best Computer Buy

By Scott Jackson

You've just made the best computer buy that you have done in a long time. A real screaming hot system with plenty of ram and the new Vista operating system is something you have been dreaming of for a while. You begin exploring your system to find all the features this new baby has. Fast speeds, new graphics, new programs, widgets and tons of web surfing power are what you got in your new system. You feel like you just got a Ferrari. But remember, even those sports cars need tune-ups and maintenance every once in a while.

Web apps leave little cookies, adware, spyware and other bits of code. When you install and uninstall programs they leave parts of themselves on the computer, in the registry and the operating system folders. So you have to tune up your new system every once in a while and begin performing regular maintenance after you get your best computer buy.

Here are some tips to get you started:

1. Clean out the history and internet cache. This will free up valuable space on the hard drive and you browser will run smoother.

2. Defrag the system on a regular basis. Defragging puts all the files in a uniform order. It takes a while on larger hard drives but improves performance.

3. Use a registry program to clean and maintain the registry. This will remove those left over bits of code and correct active x problems and other registry quirks.

4. Scan for viruses. You should get a good virus and firewall program (many are available from very expensive to free programs) and scan on a regular basis to keep you computer running safely. You should also update the virus library quite often to keep up to protect your system.

5. Scan for adware and spyware. There are many good programs out there that will keep an eye on your system to protect you and your computer. They can rob you of computer performance and can even steal information off your system with really bad ones. You may not even know that you have them. Just visiting some sites or download some web apps will put them on your system.

You just spent a ton of cash on your best computer buy so you want it to last as long as possible. Protect and maintain your investment and it should last for a long time to come. You can set many of these safety procedures to automatically happen from your operating system and the program that you got with your computer or purchased to take care of them.

Down time due to bugs, little hard drive space and a ton of other preventable issues can cause you a ton of grief and headaches when a little preplanning and maintenance would have taken care of this.

Scott Jackson has been working and maintaining computers for over 20 years. He started with the old Comodor Vic 20 computers and has been building his own systems since. Stop by his page and give a try to a registry maintenance software he recommends. Try if for free and see if you need to have work done on your registry.

Better Computer Performance - 9 Free Or Inexpensive Fixes

by Jed Jones

Poor computer performance by your Windows-based machine can sneak up on you gradually. You may find its performance deteriorating increasingly until one day you realize you must fix it or buy a new one. Signs of poor performance can include applications running very slowly, programs closing or freezing up suddenly, and a generally slower response time to OS (operating system)-related commands. I have compiled 9 fixes for you here that you can leverage right now to greatly improve your computer's performance.

Fix #1: Download and run MS Service Pack 2:

Every operating system requires patches and upgrades by its maker from time-to-time, with Microsoft XP being no exception. While Service Pack 2 was released in 2002, some people with older systems are still not running it: make sure your computer is. You can download it FREE from Microsoft's Web site.

Fix #2: Run the Disk Cleanup utility:

Your computer likely has a number of unused and unneeded files that take up valuable space on your hard drive and slow performance. Run your FREE, built-in Disk Cleanup utility to automatically remove these files. Find it by going to: Start | Programs | Accessories | System Tools | Disk Cleanup and following the prompts.

Fix #3: Defragment your hard drive:

Over time, your computer will store files in an increasingly inefficient manner on your hard drive, affecting file retrieval times and other performance factors. To fix this, you need to defragment your hard disk drive. To do this for FREE, just go to: Start | Programs | Accessories | System Tools | Disk Defragmenter. First, highlight the drive you want to clean up (e.g., C drive) and choose Analyze. Once complete, choose Defragment. Note that the defragmentation process could take up to an hour or more, so do this during a time when you can step away from your computer.

Fix #4: Run an anti-virus tool:

Computer viruses are malicious programs that drastically affect your computer's performance, either all at once or insidiously over time. You can stop a virus attack by installing and running anti-virus software which performs regular scans, locates the offending viruses and quarantines them.

Fix #5: Clean your registry:

Your computer's registry is a tool that most non-computer specialists never see but which is vitally important to computer operations. Your registry stores settings and options for your hardware, operating system, and other software. Unfortunately, given its fundamental role in the performance of your system, your registry is often the target of attack or infection. To thoroughly and automatically clean your registry, run a regular registry scan using a registry cleaning tool. I recommend RegCure, which recently found 1,626 problems with my registry (ugh!), is cheap and easy to use.

Fix #6: Run anti-spyware software:

Spyware is computer software that installs itself in your computer and performs a number of unwanted functions, including monitoring your computer usage and interfere with your control.

It represents a real threat and has become a significant problem in recent years. Fortunately, fixes are easy to find and include a number of free and inexpensive anti-spyware programs. Try SpyBot Search & Destroy. Get it FREE online.

Fix #7: Increase your computer's memory:

Today's applications require more and more memory (RAM) to run. If your computer is more than two years old or if you selected the minimal memory option upon purchase, you might benefit from adding another 1 GB or more to your computer. Check online or at your local computer dealer for pricing.

Fix #8: Clean your hard drive:

More comprehensive than the Disk Utility tool introduced above, cleaning your hard drive with professional cleaning software is a great way to improve performance. Try CCleaner for FREE by doing an online search.

Fix #9: As a last resort, re-format your hard drive:

If after trying all of the above items and your computer still performs poorly, a last resort is to completely reformat your hard drive. Warning: proceed with caution since this action will erase your entire hard drive, including your operating system (OS)! If you decide to take this route, consult an online tutorial for how-to steps. At minimum, remember two things: be sure to back up all of your files and applications and retain a copy of your OS on CD so that you can re-install it later.

How Large, How Fast? Choosing the Right Hard Drive Size and RPM

ฺBy:Tim Childree

One necessary and extremely important component of computers is the hard drive. The hard drive stores your games, applications, music, pictures, videos, and documents. As such, you should be sure the notebook computer you're thinking of buying has a hard drive that can give you the storage and performance that you need.

There are two important considerations when looking at hard drive specifications for your computer notebook: hard drive size and hard drive RPM.

Hard Drive Size

Hard drive size simply refers to the data storage capacity of a hard disk drive. Desktop computer hard drives offer sizes of up to 500 gigabytes (GB), while notebook computer hard dives offer sizes of up to 160 GB. Notebook computer hard drives are more expensive than desktop computer hard drives with more than twice the capacity of the notebook hard drive. This is due to the engineering difficulties inherent in making high-capacity hard drives for the smaller notebook computers form-factor.

A notebook computer's hard drive size indicates how much data a notebook computer can store. If you are interested in storing large amounts of movies, pictures, or music, you want to go with a larger hard drive to avoid running out of space.

A hard drive's size has very little to do with its performance, unless the drive is almost full. The Windows NTFS File System requires a minimum of 10% of the hard drive to be free space for optimum performance, and it frequently requests as much as 15%. This means that, on a 40 GB drive, Windows prefers that you use a maximum of 34-36 GB, leaving 4-6 GB of space unused. On a 160 GB drive, Windows prefers that you use a maximum of 136-144 GB, leaving a massive 16-24 GB unused. If you start to go over these Windows storage limits, you may notice your computer's performance taking drastic hits.

Hard Drive RPM

Hard drive RPM is a hard drive's rotational speed, measured in revolutions per minute (RPM). Desktop hard drives now have speeds as high as 15,000 RPM. Notebook hard drives, on the other hand, currently have an RPM ceiling of 7200 RPM.

A hard drive's RPM indicates how fast the drive's spindle will move or how fast the hard drive platters will spin. The higher the spin rate is, the shorter the seek time and latency will be. This translates to quicker data access and transfer.

How Large and How Fast

The greater the free space and the higher the RPM, the better your notebook computer's performance will be, so go for a slightly-more-than-comfortable size and the highest RPM for your notebook computer's hard drive. A large hard drive gives you the option to expand in the future, and you can never go wrong with a notebook computer that can give you fast access to your stored data.

It is even more crucial that you go with the top-of-the-line hard drive size and RPM for your notebook computer if you are fond of computer games, you have a lot of multimedia files, or you want to be able to easily upgrade your programs. These games, content and programs take up a lot of space. A high RPM hard drive can also cut down on game load times, giving you more time enjoying your games and less time staring at loading screens.

How To Choose A DVD Recorder

by: Robert Barnard

Ah, you think, as you take a look at your year’s old collection of VHS tapes - all the enjoyable hours you spent watching each movie and deciding if it should be added to your home theatre selection. What a great collection of movies. But wait - technology has not only crept up on you, it’s left you in the dust. DVD’s are the gadget of the moment - they’re faster, cleaner, have better sound quality and way better picture quality. Oh, no, you think - you’ll have to convert all those old VHS tapes to DVD if you want to “keep up with the Jones.” But which DVD recorder should you choose? Which will give you the most features for the lowest price?

A DVD recorder is different from a DVD player - as the name would indicate, a DVD player does just that - it will play movies for you as long as there is battery life left or electricity to power the unit in your home. A DVD recorder, on the other hand, allows you to copy DVD’s from the original media to a recordable DVD that you can then add to your collection of movies - replacing all those VHS tapes that are collecting dust. DVD recorders also can record directly from your TV to a DVD.

A big consideration is whether or not to buy a DVD recorder with a hard drive - no, I’m not trying to confuse you with computer jargon - it’s not like you’re buying a laptop. The reasons you might want a model with a hard drive are twofold - you have more editing options, plus you can choose whether or not to archive a recording to disc. Another feature that’s included with a hard drive is that you can pause what you’re recording as it’s being recorded and not lose any of the show since that is how the unit is made.

For a good, basic DVD recorder, take a look at the RCA DRC8060N - it comes in at just over $200, but for a relatively inexpensive machine it offers a few pleasant surprises, such as an HDMI port that allows you to connect with an HD-TV, plus in-front inputs for camcorder use. While it doesn’t offer a VCR or a hard drive, the picture and sound quality are comparable to more expensive models.

If you’re looking for a machine that has it all, you may want to consider the Panasonic DMR-EH75V - which will set you back about $375 - $400 or so. Even though it’s pricier than some other models, it offers a DVD player/recorder, an integrated VCR and an 80 GB hard drive that allows you to pre-program your recordings even when you’re not there. This model has excellent picture quality, and it records particularly well in LP mode, meaning you can get more programs on a single disc. It also offers an HDMI output jack so you can connect to an HD-TV, as well as an SD card slot if you want to display digital photos.

Samsung offers a model DVD-VR335 that runs about $280, placing it mid-range among other models. It also features an HDMI upconverting DVD recorder, with an integrated VCR, composite video jacks in and out and Dolby digital capability. It can record on most DVD media, as well as playing DVD and CD media and MP3 audio.

What’s the advantage to having an integrated VCR as part of your DVD recorder? Most people use this feature to convert all those old VHS tapes to DVD format - updating and cleaning up their movie or television show collections. End result - the vast majority of consumers who have this feature end up using the DVD recorder the same way they used their old VCR’s - taping or copying everything from their favorite TV shows to movies from their collection.

Computer Performance - Proven Tweaks to Make Your Computer Run Faster

by Gene Higginbotham

Programs run slower than they used to.

Frequent freezes or crashes.

Sporadic system instability.

Frequent blue error screens.

Requires frequent reboots because of system hangs.

These 8 simple tweaks will help clean up your computer and you'll be surprised at the performance improvement!

CLEAN UP YOUR WINDOWS REGISTRY This essential task is often overlooked but will remarkably improve PC performance. Most PC users don't even know there is such a thing as a Registry much less that that it should be regularly cleaned. In fact, Microsoft doesn't even include a cleanup tool in Windows. Every time a program is installed or uninstalled changes are made to the Windows Registry which is a huge internal database of Windows' settings. All programs, as well as Windows itself, store a huge amount of information in this database and these entries control the way everything in the computer looks and behaves. Many times, changes to a computer are not handled correctly leading to conflicts and the slowing of the computer due to a corrupted Registry. Some things which can cause this are: * frequently installing or uninstalling programs * removing a program and leaving traces behind * leftover entries from a hardware uninstall * power failure or system crash in the midst of updating the registry * unused drivers on the system * Spyware or Adware type programs that come back every time the PC is restarted The Registry can be edited manually using a Windows program called RegEdit, but woe to the novice; this is really a job best left to the experts. Instead, you need to use a special program which makes the cleanup for you.

EMPTY THE RECYCLE BIN Regularly empty the Windows' Recycle Bin thereby releasing hard drive space and helping to improve performance. When you delete a file, instead of removing it completely from your computer, Windows puts it into the Recycle Bin. You then can restore these flies from the Recycle Bin back to their original place on your computer if you should need to.

REMOVE UNNECESSARY PROGRAMS If you're like me and download a lot of free programs or free trials, after a while your computer might begin to slow down. That means it's time to remove some of the old programs you don't use any more (and most you probably only used once just to see how they work). After installing a program, if you decide you don't need it and won't use it, get it off the computer thereby freeing up system resources. Most programs come with their own uninstaller but if it doesn't you will have to use the Operating System's Add/Remove Programs feature which you can get to through The Control Panel. Uninstalling unused programs will help speed up your computer, but removing the wrong files can cause you some really big problems. NEVER, NEVER EVER just delete a program file by using the delete key; this can really mess up the Registry. Be careful and if you are not sure, ask for help from someone you know who is more experienced. If you are unsure whether or not to remove a program, it's best to leave it. Some programs leave uninstalled junk all over the Windows Registry! Therefore, to improve PC performance AFTER AN UNINSTALL, IT'S ESSENTIAL TO CLEAN THE REGISTRY.

RUN DISK CLEAN UP Windows Disk Clean Up is a great built-in utility that automates regular maintenance tasks to improve PC performance. Whenever you "surf the net", open file attachments, delete files, etc., your computer saves a record of your activity. Most if not all of these files are harmless, and are very small. But if you spend a lot of time on your computer, before long they will use up enough space to slow your computer down a tad. Double-click My Computer, right click on the 'C:' drive, then click Properties, then click Disk Cleanup. The PC will then spend a few moments analyzing. When it has completed analyzing, Windows will give you a list of areas where it has found files to cleanup. To clean an area, check the box next to it. To leave something intact, such as Temporary files, just remove the check mark next to the item and click OK. Your computer will then begin the removal process which can take a good while.

DISK DEFRAGMENTATION When Windows stores programs and files on your hard disk it saves fragments of files in the nearest empty spaces and then links these pieces together. When the computer needs to retrieve a file, it has to go through the process of chasing these links hunting down the fragments and piecing the file back together. This can really slow down a computer, especially if it has small internal memory and has to do a lot of caching and file swapping. The cure is to routinely run the Windows Disk Defragmenter which gathers together the fragments of files and puts them back in the right order in as near contiguous space as possible. This makes it far easier for your computer to find what it's looking for on the hard drive, enabling programs and files to load more quickly. To defragment your hard disk click Start, All Programs, Accessories, System Tools and then Disk Defragment. When the program has loaded, click Defragment. Before starting you need to run "scandisk" which checks for disk errors. Without scanning your disk first for possible errors, defrag may refuse to continue its defragmentation routine. The process can take over an hour. Because defragmenting your hard disk takes such a long time, you really don't want to go through the process very often; maybe every 3-4 months and it's best not to use the computer while defragmenting.

GET A HIGH SPEED INTERNET CONNECTION If you spend a lot of time on the internet, a high speed internet connection is a must. It is more expensive, but for most people the savings in time and effort is worth the added expense. Some of the advantages to having a high speed internet connection: faster surfing, web pages open more quickly, files download faster, and if you send or receive large files, like pictures or video, they will open in a flash when compared to a slower dialup connection. If you're already spending money for your dialup connection (through your phone line) then you'll find DSL to be comparable in price, and a lot faster. A cable internet connection might cost a little more, but it is usually the fastest type of internet connection you can get from home.

REMOVE SPYWARE & ADWARE If you've ever had spyware or adware on your computer, you know how frustrating it can be. All kinds of strange things happen: your homepage changes seemingly on its own, unwanted and inappropriate popups, unfamiliar icons, and the list goes on. Spyware or Adware are files that are often downloaded onto your computer without your knowledge (or at least without you knowing what they really are). Unfortunately, many of these programs "sneak" their way onto your computer, and avoiding them entirely is difficult, especially if you spend a lot of time on your computer, surfing the Internet and downloading new programs and files. There are ways to remove these unwanted files from your computer. Check out these 2 adware/spyware removal programs that are simple to use (both are free): Ad-Aware http://www.lavasoftusa.com/support/download/ Spybot http://www.safer-networking.org/en/download/index.html Adware/Spyware continue to be such a problem because most of these programs make money for the people creating and spreading them. If you find these unwanted intruders on your computer, don't panic. In most cases, it is not vicious like a Virus or Worm. You just have some extra "junk" on your computer. However, keeping it off of your computer will help it perform more efficiently.

ADD MORE INTERNAL MEMORY (RAM) AND A LARGER HARD DRIVE If you have done all/most of the above and your Computer's performance is still so bad that you are thinking: Gee, I guess I am going to have to buy another computer! If everything else about the computer is satisfactory to you, then you might consider an Upgrade. If the PC is only a couple years old, it can easily be upgraded. If you still have the manuals that came with it, you can determine the type of memory it uses and buy it off of the internet at a good price. If you don't have the manuals, take it to Best Buy or Circuit City and ask them if it can be upgraded (or take the model and make info to them). Their upgrade cost is not that bad and certainly cheaper than buying a new computer. Another alternative: if you know a High School Kid who has taken some computer courses, he/she can probably do it real cheap. I have personally maxed out my computers memory and added another hard drive. Together with the items above, my computer runs like a "Tiger chasing a Scared Bunny". I hope this has been of help to you. I have prepared a brief video which depicts the frustration I was having with my computers performance and how I Cured My Computers Performance Problems.

Data Recovery Services & Solutions

by Richard Cuthbertson
Data recovery services & solutions are required when computer users are no longer able to connect to there data under normal operating conditions. Causes of such failures can be broken down into four main categories.

1.Diagnosis Often Neglected this very important first step of the recovery process can make the difference between failure and success, it is worth noting that items 3 and 4 can be incorrectly diagnosed by untrained attempts.

2. Logical Failure. File system corruption directly affects the logical integrity of the user's data and their ability to access it under normal operating conditions. Common situations are deleted or virus affected data.

3. Physical failure. Noisy hard drives such as clicking, ticking or knocking noises can strike fear into anyone who has important data on their drive.

4. Microcode Failure. Magnetic storage media or hard drives or disks as they are more commonly known as have there own internal operating system or code to be more precise, which is very complex and deals with such issues as bad sectors reallocation and physical to logical geometry, this is the most complex area for recovery simply not repairable by ordinary means, failure types or indications of such are the hard drive is not detected in the bios, or wrongly reports the family name of the manufacturer. Occasionally hard drive media can exhibit a physical failure such as described above if misdiagnosed and internal work is carried out on the head stack assembly, this can severely compromise the procedure, again professional diagnosis is needed.

Common myths, dangerous advice, the big freeze... Placing your hard drive in the freezer to recover your data is not a good place to start, or finish on for that matter; however the internet is littered with examples of such practises with alleged successful outcomes. Hard drive media are based on very precise control mechanisms down to a sub micron level freezing the media will destroy this precision, not to mention the water content that is now inside the disk enclosure... Hit or tap the media to make the hard drive work, contrary to popular belief this will not work either. Open the drive up for a quick look, you may see the problem and be able to fix it, highly unlikely that any untrained computer user will discern anything; in fact the very opening of the media could yield the media now unrecoverable.

Clean room, what? Are the necessary? Magnetic storage media are assembled in clean room environments which allow for strict control air particulate, temperature and static control. As this process is required to build, design and assemble the media it requires nothing less than this equipment for repair, any company that does not have this equipment could cause further damage to your media.

Lost data? Now worries. Losing data can be very stressful and an emotional time, here are a few basic tips that will help avoid this. Keep the media cool via cooling fan which connects directly to the hard drive assembly. Connect the computer through an UPS for continues smooth power supply. Backup, backup and backup, preferably to further hard drives and a form of optical storage such as dual sided DVD.

How To Troubleshoot a PC That Won't Turn On

From Tim Fisher,

It's a dreadful way to start a day - you press the power button on your PC and nothing happens. Do not fear because all may not be lost! Follow these simple steps to determine why your computer won't turn on.

Note: It is very important to troubleshoot any issue beginning with the most likely and easily testable problem so be sure to follow these steps in order.

Difficulty: Average

Time Required: Anywhere from 10 minutes to a few hours depending on why the computer won't turn on

Here's How:

1. As silly as it may sound, the number one reason why a computer won't turn on is because it wasn't turned on! Before starting a sometimes time consuming troubleshooting process, make sure you've actually turned on both the computer case and the monitor using the power switches on the front of both.

2. Many computers have power switches on the power supply, located on the back of the PC's case. Check this switch, often called the rear power switch, and make sure it is turned on and that the correct voltage is set and then attempt to power on your computer again.

Tip: On is indicated by the "I" symbol and off is indicated by the "O" symbol.

3. Check for loose PC and monitor power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.

4. Perform a "lamp test" to verify power is being provided. Your computer isn't going to turn on if it's not getting power so you need to make sure that the power source is working properly.

5. A damaged power supply could be preventing the PC from being properly powered, an excellent reason why the PC won't power on.

Do a quick test of the power supply by holding your hand behind the power supply fan located at the rear of the case. If the power supply is working, you should feel air from within the case blowing against your hand. If not, you may need to replace the power supply.

Tip: Is the power light on the front of the computer's case on? If you've turned the power switch on but the light is off, this is another good indication that the power supply is the cause of this issue.

6. Over time, internal components and the cables that connect them can wiggle loose which can often time result in a computer unable to power on. Try reseating the following and then try to power on the PC again:
* Reseat the internal cables
* Reseat the memory modules
* Reseat the video card
* Reseat other expansion cards

7. Reseating the CPU may also be necessary but should only be attempted if the reaseating of all other components is not successful. This is due to the fact that this process is a little more involved and can run a small risk of damage to the CPU (this isn't a big concern if you're careful, so don't worry!).

8. Check for causes of electrical shorts in the computer case. This is often the cause of the problem when the computer powers on for a second or two but then powers off completely.

9. Hearing beeps? You haven't gone mad - your computer may be using a beep code to tell you exactly what's wrong! Troubleshoot the beep code and service the computer as necessary.

10. Most monitors have a small light next to the power button that can change between various colors. If the screen is blank, this light is your main source of information about the monitor.

If this light is not on at all, double-check the power switch and connections (Steps 1, 2 and 3) and also make sure the monitor cable is securely plugged in to the video card port on the back of the computer case. If the light is still off, replace the monitor. If it comes back on, try starting your PC again - a loose or unplugged monitor cable may have been the issue all along.

11. An amber or yellow power light simply means that the monitor is not receiving any information from the computer. In and of itself, this doesn't tell us much.

On the other hand, if the light is amber or yellow, the computer power light is on, and the hard drive is active (making normal sounds and hard drive activity light on the computer case is blinking), the computer is probably starting normally but the video card is not sending information to the monitor. Replace the video card.
Beep codes usually sound when a video card has malfunctioned (Step 9) but this is not always the case.
