This has happened to me twice. In the middle of the night the PC suddenly turns on and wakes me up. Scares the heck out of me. I turn it off immediately. I have anti-virus and a firewall security package. Testing shows no point of entry and no sign of any usage by an outside source. I swear its possessed! Any ideas???
