Hi All,

A problem has occurred with my PC and I'm hoping someone can advise.

Of late working both on and off line, my PC has started to just switch itself off as if, the electricity supply or socket switch is turned off. There is no warning.

Sometimes just rebooting it, can be annoying, as it switches off seconds into the reboot. Then again, the PC may run for a couple of days without a hitch.

I have noticed that it tends to switch itself off when an anti virus scan runs, I'm downloading something, playing music or video. Even looking at Google Earth can be a problem - moving the mouse and the screen freezes for a second or two, then 'catches up' or 'jumps' to where the mouse should have moved the screen image. It frequently turns off when this happens.

It is as though anything involving the computer to work harder than just reading a web page or emails prompts it to shut down.

Any ideas on what the problem might be? I'm assuming that the electricity supply is operating normally. The problem started when I moved address. Only at my current home did the problem emerge.

System make/model...and manufacturer?

How much RAM installed?

How many partitions? Size of each? Free space on each?

Have you checked to ensure that all fans are working properly? (Open case and take a look).

This is a desktop?

This type of rebooting behaviour is often caused by your computer overheating. You can check your system temperatures with SpeedFan, which should give you an indication of whether your system is running too hot.

Also, I would recommend that you open your computer case and make sure all the fans are spinning okay and that there isn't an excessive amount of dust in there that would impede air flow. See the following Bleeping Computer tutorial for guidance on cleaning inside your computer.
