PC boots up by its self

I have windows XP Home, zone alarm and AVG anti virus,I also have broadband. My PC keeps booting up by itself, any ideas what to do

Do you still have a modem connected to the telphone line? If so it could be that your bios is set to "wake on ring"

Do you have another machine connected to it on a network? If so, bios could be set to Wwake on LAN"

Is it only after a short power outage? This happened with my son's PC, if so take a look at the power management settings.

Thanks for your response done all what you said still the same, some times it does it aftyer 20 minutes some times it goes for days then boots up

Could be a faulty power switch that reacts to a small power surge or spike.

In addition to shutting down, turn the rocker switch on the PSU at the back of the PC to off and that will prevent it happening again.

Thanks for this, so you think it could be hardware problem, because I have a warranty, I was more concerned that it was a virus etc

More likely to be hardware - not quite sure how it could be virus, they need the PC to be on to run a piece of code. They cannot start the machine.

If still under warranty, get in touch with the supplier/manufacturer.

Mine does this. I now always turn it off at the mains after I shut it down, which also reduces my electricity bill a little. I've been told that in standby, a computer takes more power than you might think, although a lot less than it takes when it's on of course.
