Is this a Windows XP problem or BIOS/CMOS/PSU?

Hoping to get some help here. About two months ago my system started acting weird. When I shut down from the start menu it does what it is supposed to do. However, about 20 min to 30 min later it will restart on its own. I have no idea why. I have gone into BIOS and disabled all wake ups. I have gone into power management and disables/set properties accordingly. I still turns itself back on after being shut down for about 30 min. I don't think it is a power supply problem because when it turns back on and boots to the BIOS password (set password in BIOS) I can turn the system off using the on/off button on the front of the tower and it will stay off until I decide to turn it back on. Something is triggering the BIOS/CMOS to turn back on. I wonder if it could be a virus or program on my system? I have run AVG and it found no viruses. I currently have NoAdware, AVG, and StopZilla. I can do a HijackThis log and post it here if anyone thinks it might be a software conflict. Any ideas how to isolate it. Its driving me freakin' nuts. Thanks! :tazz: :)

I could be a corrupted bios, or a virus hit it. You might try reflashing the bios. Note: Follow the bios flashing steps on the motherboard manufacture's site to a "T"... or... you may end up with a dead machine.

Thanks. I reflashed it the other day but it made no difference. Any other ideas?

OK, here is what I did to try and narrow this problem down. Last night I disabled StopZilla services (don't think that really made a difference). I had read an article that said the power button can sometimes do this. So I pulled the front panel pins off the MOBO for reset, shutdown, and led light. I also pulled out the phone plug (eventhough I disabled wake on ring in modem and BIOS). I shutdown the system and checked back after a couple of hours and it was still down. So I plugged everything back in (what I should have done is add one component at a time - will try that tonight) and rebooted, and then shut down. I checked back again around two hours later and the system was still down. So I figure it was a lose reset or on/off plug on the MOBO. I woke up this morning and the system was on :tazz: It seems that it may be one of those components. Any ideas? Thanks.

OK. It ended up being a bad modem card. Will get a new one today. Just thought I'd pass that on.

Your modem card may not be bad, it may just be set to powerup on LAN.

yes Tyger is right...
are you sure you dissabled the "wake on lan" feature from the BIOS?

Yes, I am 100% sure that I disabled it. I initially pulled the phone cord from the modem but it still kicked on after a while. Then I pulled the whol card and it has continued to stay off. Bad cap or other component on the modem card?
