windows open on themselves
every hour or so the pc makes a beep (not from the speakers a hardware type beep) and it opens a my computer window or a search window. At first I thought virus but I've scanned it with 4 or 5 different scanners and nothing shows up.
I donít know if this would have anything to do with it but yesterday when the cod 4 multi player icon was click on the pc shut down instantly (as if the power switch had been flipped) and then rebooted itself.
It rebooted ok and that evening I played cod and all though the game I had the occasional beep.
shut down the game closed the odd window that had opened and went to bed. When I looked at the pc this morning (pc stays on all night) as I had heard it beep the screen had a dozen or so windows open.
So what do you think is wrong and how could I fix it
