Computer Starts Alone

[zapjb]

Me thinks OP has their computer on standby or hibernate. Not OFF. And I still think their computer is somebody elses bitch (bot). Plus I like saying that.

there is something else that u can prove ... if there no virus, and no one program turning on ur computer, try going into settings on ur mother board .. and maybe there is a value named rtc alarm, it must be disable ... i dont think it's what happened to u but it can be a solution.... Luck

I had the exact same problem. My computer would start up all by itself. At first I thought it was a virus or trojan, but I did several scans and nothing came up. Then I thought it was some hacker doing something, so I would unplug the ethernet cable but it would still do it. Then I thought it was the Wake On Lan feature in the BIOS but I had that turned off. After I reformatted, I finally figured out what it was. It was the damn controller card drivers.
