Computer shutting off during the night
This has happened 2 nights now. I'll go to bed around 3 AM, wake up at 11, and my computer will be powered down. I have an Antec Truepower 550W PSU. I've had this build for over a year and have not had any problems.
Is this something with the power supply? We haven't had any storms or anything like that.
Or is this something from windows? Did I get my first virus/trojan/something nasty? I am guarded with norton and have scanned with spybot and adaware. Is there something to look at to see why it powered down?
