Hello. Smile

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. Smile

Could be virus, mobo, psu, cpu, or maybe even ram...

Need to take a methodical approach to it.

I think I would start with running a Linux Lice CD to see if that suffers the same power-off fate. If so, then its hardware related..., if not... then software related... (probably).

AS Tony said, could be anything.... overheating is another possibility. Had a few systems come in with that issue... bit of thermal paste, blow out the hs/fan and away they go again :)

Thanks for the replies. Smile

I just remembered something else that their computer does that might help pin point the problem.  One night while I was on the phone with my girlfriend, she held the phone up to the computer, and it was making a crackly, buzzing noise (sort of an electrical sound.  I'm not sure what it was, but it didn't sound very healthy to me.

Take out virus option if computer completely powered off itself. Virus force pc to restart. I dont know about any new blasts though.
The sound may be coming from Power Supply. Take a look at it whether fan is running or not?? If not...change the Power supply.
Overheating can be a problem...Remove one side casing cover and see how PC behaves...if it works fine then overheating may be one of the reason...
