One of the main reasons why a computer may keep shutting down is overheating. If the computer is overheating, it will automatically shut down in order to protect those vital parts that may otherwise be damaged by the heat.


So shutting down is a good thing. It helps protect your computer and your files. It's a safety measure not a fault!


Even the most non-technical computer user knows that a computer makes a noise from time to time. That noise is a fan designed to keep everything cool, and it works much as a thermostat may do on your central heating system. When the heat in your machine reaches a certain temperature the fan (or fans) will kick in to fan cooler air over the components, and as the heat reduces to the correct level the fan will switch itself off again.


If your fan seems to be coming on a lot, and staying on longer, it's a sign that you need to check things over.

The most obvious place to start is the vent holes or grids. All machines have them, and they're designed so that the fans can suck in cooler air from outside the case. Desktops are particularly susceptible to getting these holes blocked with dust. The unit is placed on the floor under a desk and forgotten about. It's time to bend your back and check the vent holes.


I've seen people take a duster and wipe a lot of dust off these slots, but if you do that, all you're really doing is pushing the dust to the inside of the case. Far better than to take a hoover to it and vacuum all the dust up.


Whilst you've got the hoover in your hand, take the side off your case and take a look at the fan (or fans) and you'll probably find that these are covered in dust too, and that makes them far less efficient.


WITHOUT TOUCHING ANYTHING WITH THE HOOVER, give the whole lot a good hoover up and make sure all the dust is sucked up off your fan and from all the corners of your case.


Nine times out of ten these housekeeping measures will have your computer up and working OK in no time at all. It's very rare for a computer to keep shutting itself down due to software or hardware failure, and an accumulation of dust induced overheating is far more likely to be the problem.

Curing this problem first is both cheap (as in free), effective, and usually all that's required.


If the power unit appears to be working, the processor fan working, lights are on at the front of the computer but there is no sound from the drives and none of them appear to be working, it’s easy to assume that the motherboard has gone. BUT, before you rush out to buy a new motherboard you should try the following:


The graphics card may have been knocked or become displaced. Take the graphics card out and then put it back, this may cure the problem. If you’ve got a spare graphics card, try a replacement.


Try taking out the battery for a few minutes before restarting. Try a new battery if you’ve got one.


The memory may have been knocked or become displaced, or a memory module may have developed a fault. Try removing, replacing the modules one at a time, and try to start up with and without particular a module.


All the above faults sometimes give symptoms similar to a motherboard fault, but can be fixed a lot quicker, and cheaper, than replacing a motherboard.

You push the power button on your computer and 5 minutes later you're finally ready to start computing. It seems as though it takes forever and a day for your computer to get going, why?


Most likely, the main reason your system is dragging the ground is because of all the junk that runs in the background that you don't see. These are applications you may have installed over time.


Such utilities as scanner drivers, and hard drive monitors can swallow up memory and cpu processes, not to mention adware and spyware creeping into your system. These affect both your computer's boot up process and performance during normal operations.


Another reason for slow pc boot up and performance may be the simple fact that your computer is aging. Computers running Windows XP and Windows Vista with CPU speeds of 900 MHz or less are good candidates for slow operation. These systems often have inadequate RAM Memory as well.


OK, so you’re no doubt asking, how can you correct this ever present, nagging problem? If your system was purchase when dinosaurs roamed the earth, consider upgrading by adding more memory, a larger hard drive, and if possible a faster CPU.


You can free up hard drive space by deleting files and applications you don't use often. Improve performance by not overlooking basic pc maintenance. Running scandisk and Defragment are crucial to pc performance. And try third party memory management programs.


Running scandisk will find and attempt to correct errors on your hard drive. System Defragment will free up hard drive space by re-arranging files in an orderly manner. This allows the CPU to find files much faster and not have to roam all over the hard drive to load files into memory.


You can get more bangs for your buck by purchasing a faster computer however. When adding the costs of components and the increase in speed and performance you will gain, you may come out better to purchase another system.


Windows operating system have a utility named Msconfig that can display programs that boot up and instantly run on your computer. To start Msconfig, select Start, Run, and type "msconfig" without the quotes, in the Run dialog box. Msconfig does not show all programs running in the background however.


If you have Windows XP as your operating system, try to delete all files in the prefetch directory. Windows XP Professional monitors files that are used when the computer starts and when you start programs.


When Windows XP Professional monitors these files, it prefetches them. Prefetching data is the process whereby data that is expected to be requested is read ahead into the cache. Prefetching boot files and applications decreases the time needed to start Windows XP Professional and start applications.


These files if not deleted will lower system resources and slow pc performance by loading programs that are no longer being used.

To delete these files, open C, your system drive, and go to windows/prefetch.


Delete all files or at least those more than 3 weeks old and, reboot. Try to check to see if your computer and the CPU Chip are not overheating. Excessive heat will cause your system to perform much slower. Make sure your computer is well ventilated.


And when it comes to correcting slow computer performance, you can be your own worst enemy. And just how is this? The word procrastination means to put off today what we can do tomorrow. Such simple tasks as running scandisk and defrag are often put off until a more convenient time.


Don't let procrastination or anything else get in the way of boosting the performance of your computer. You'll thank yourself many times over when you see the results. You will also have the knowledge to help others boost their computer's performance as well. And that can always be a blessing to someone.

Tips for Speeding Up Your PC

Few things are as frustrating as handling a slow, sluggish computer. When a computer is brand new, it works wonderfully well. Over time, though, its performance can slowly start to worsen. This happens for a number of reasons, but the biggest culprits are things like spyware, adware and other computer threats that are unwittingly downloaded along with other content while online. You don’t have to download thousands of MP3s, movies or other items to experience these issues, either - no one is immune to them. Instead of accepting the situation, there are many techniques and strategies that you can use to make it better - a few of the best ones are outlined below
