Hi Debbie, I think I'd be inclined to see if your friend can help locate some CPU temperature monitoring software to establish if the CPU is in fact overheating. Also, if you are able to check the event logs for the time of a failure, you might get some clues there. I have seen systems begin to overheat when something like Windows Defender's scanning process kicks in, especially if you are running other applications at the same time. I usually tell mine to scan overnight. George.

The fans are working but there is space for another fan so we were wondering whether we got another one and wondered if that might help.

This is one of the most common reasons for a system powering off. It it's a desktop, it usually pays to have the case opened, and gently clean it out with a hoover. Laptops are trickier as you cannot really open them up easily, so it's a case of sucking out what you can. George.

I want to keep this computer running for a few more months until I can afford to buy a new one early nest year. Regarding Service Pack 3? How can I stop it from downloading and is it necessary to download it? We still haven't got to the bottom of why the computer switches itself off so don't want to risk it downloading again. Could I do it via disc instead?
