computer is turning itself on and off

[immortal07]

alright. so heres the story. my other computer has been acting funny for a while it started turning itself on and off around christmas time, and it was brought into the shop. the guy told us it was a power supply and virus problem. so he replaced the power supply and said he deleted the virus. about a week later, it started doing it again. it was taken back and the virus was deleted again. he said it was very deeply rooted.

about an hour ago, a week after we got it back it started doing it again. one of my friends said it might be a BIOS problem, but i dont really know a whole lot about computers. any help?


FYI, there were torrents downloaded on that pc, but nothing had been downloaded a couple months prior to the problem occuring.

thanks.

More details of your system would be handy.  Which OS, do you have anti-virus & firewall installed, what's your hardware setup :-?

Can you check your component temperatures :-?

Check the BIOS and see if your computer is set to turn on at a specific time. It's possible that somehow, a time was set for the computer to turn on in the morning... Also, I suggest getting yourself some virus protection.

Which OS - I'm presuming XP.

Sounds very like the big bad Sasser or MSBlast.   Have you installed all XP updates from MS, have you installed SP2 :-?

Make Google your friend - have a look here.

Stop your irrelevant drivel, Mac.

he said it was very deeply rooted.

Which means, "Oops, I cocked up.  I don't really know what's wrong with this PC, but *censored* I'm going to charge you for my time anyway."  Did he actually test the power supply before replacing it?

Anyway, you say that the PC is turning itself ON as well as off.  That's not virus activity.  A virus can only perform its devious duty when the PC is running.  When you're turning the PC off, is it fully off, or just suspended?  If it's switching itself on, when fully off, then yes your friend is right - this is a BIOS issue (at least partly).
