Mysterious shut down
Not really sure if this is a software problem or hardware, but a certain event made me think it's hardware. While I was on the computer, all I was doing was talking on MSN, my computer shut down with no apparent reason. Not only that..after, I couldn't turn my computer on by pushing the On switch. I actually had to unplug the computer from the power supply and then back in.
Is this a common problem? What could have caused this? Is it something that's serious?
