I'm asking a question on behalf of my girlfriend. Something odd has been happening to her computer (well, her mum's, actually) quite a lot lately. What's happening is that every so often (not every day, as far as I know...) in the middle of what they're doing, the computer just turns itself off for no given reason.
We both thought that maybe it's something to do with the power supply, but don't know for sure. I had a spare ATX we could've used, but I gave that to a friend a while back (oops!).
Any ideas what the problem may be, and what my girlfriend (or her mum) can do about it? Thanks.
