but most might point to BIOS settings. You could have it set to power back on after a power failure. As such, a drop in your line voltage could trigger the restart. Another could be it's set to "wake on modem" or other device. You may also have it configured to restart with the keyboard or mouse. Do you have pets? These could be by choice or by chance.
OK, I'm sure there is an easlily understood reason for this, but my PC turns itself on. I have not discovered a pattern yet. But I will shut down in the p.m. (windows xp sp2) and sometime early in the a.m it will have turned itself back on. Likewise while I'm at work. Whats the fix?
