For a few weeks now I've been having this problem where my computer screen will randomly go black for 3-5 seconds. Sometimes when it comes back there are visual glitches in whatever was showing on the screen. It may or may not be related to my Windows Media Player, because while viewing files, the progress bar at the bottom stops moving while the actual video does not. When the video is done playing, the screen "blacks out," then "comes to."
I've been running spybot, ad-aware, and my norton anti-virus frequently, and there doesn't seem to be anything showing up.
If anyone has any idea what could be causing my computer to temporarily freeze, I would be very appreciative!
