By Tauqeer Ul Hassan

Anyone who has been around computers a lot will definitely experience its shutting down. There are dozens of reasons why a computer shuts down and each reason stems from a whole lot of PC issues. If one want to avoid it then it's better to know first what kind of shutting down is going on.

There can be several factors that can cause a computer to shut down automatically. Virus is one of the factors that could have corrupted the system files and device drivers. If this happens, then the PC would have to be started on safe mode by using the administrator account. The system will need a scan by using anti-virus software to diagnose and remove the infected files. Other problems that can cause a PC to automatically shut down may be overheating, due to dirt and dust or the power supply.

If the computer shuts down because of overheating, it can be prevented by applying thermal gel over the CPU. This gel will not cause the machine to short circuit but it is safe to use and effective in keeping the computer's internal temperature low. If the PC shuts down because of dirt and dust, then its fan needs to be checked if it is working properly.

The fans blades have to be checked and a blower, soft brush or vacuum cleaner can be used for cleaning the dust. If the reason if power supply, then maybe there is a loose plug from the power supply or it could be that a required and proper power voltage regulator is not being used and the electric current has been randomly fluctuating in the area. It's better to stop using the PC temporarily in this situation because random power fluctuation can damage the PC's power fuse.

For troubleshooting the problem of computer shutdown, the issue has to be resolved by following some steps. The PC has to be started first and then the Control Panel has to be opened. Performance and Maintenance icon has to be clicked. Power Options has to be clicked and then the APM tab. The box of Enable Advanced Power Management Support should be checked and then clicking the OK button.

An advanced configuration power interchange is present in some computers that shows completed message on the screen before the PC shuts down. It its not there, then the one that has a HAL should be used; it is installed in computers that support APM only. The ones without this do not turn off even when they are shut down. PCs with ACPI have an ACPI-compliant BIOS that allows the PC operating system to turn off its power supply automatically.

These causes are not wide range and there may be other many reasons that can cause a computer to keep shutting down. Finding the real cause can take some time. It will be much better to get a professional's opinion on how best to fix the problem.
