IT Queries: Computer problems answered

My PC has been turning itself off a lot recently. It used to run fine but over the last couple of years has become very ‘buggy’. One of the more recent problems is this turning itself off, as if there’s been a power cut. When ive been using the PC for a while it will switch off, or if im watching a DVD it will usually switch off at a similar point in time on the DVD.

Computers shutting down of their own accord is almost always due to an overheating component, usually the power supply but sometimes the CPU or chipset due to a faulty fan.

This is easily fixed by swapping out the power supply or fan. You can ask a computer tech to do this for you.

It can also be something defective is connected to your computer, you can eliminate this problem by disconnecting everything; printers, Internet, modems and USB devices.

If you do get a new power supply, make sure you get one rated at least 400W as these tend to be more reliable and many systems are chronically underpowered.
