Hi. I occasionally get a strange & highly annoying problem with my pc. While surfing the net or using any sort of media player, the text & pictures become really big & the windows overlap each other. My programs keep running but I can't see or do anything & therefore have to restart the pc. I figured that it must be a nasty virus of some kind but Norton Anti-virus & several anti-spyware programs can't find it. Any ideas on what it is & how I can fix this? Thank's.
