I have been noticing a lot lately that I would come home from work and the PC is up and running when I know it was off when I left for work in the morning. I checked the bios to see if Wake on Lan or Wake on Ring were enabled (since Wake on Ring would cause my old PC to boot when the external modem picked up a ring, but that was back in 1999) but I know they are not enabled. No one I know uses my PC and I have no settings in windows to cause the wake up like that. This is starting to worry me a bit. Does anyone know what could be happening?
