once more, ill keep doing this because i spent a lot on this computer, Iv been having this problem for some time lately. At first i thought it was a over heating problem with the 8800 gtx which i know they sometimes have and it being summer time, so i cleaned out my computer case of all the dust and cat hair and that seemed to work for a couple of weeks then it came back. Now i looked in the case and cleaned it out and still happens. Now what happends after i play a game like css which isnt realy resource hungry but after i close the game shortly after words i start a new game and a whole lot of little white pixels start popping up and going away realy fast, both in game and on the desk top, and then a little while after words just randomly my screen go black for a second or two and goes back to normal. i can still hear task in the back ground i just cant see them. just restarting my computer fixes this, but im worried in the long run that there may be more complex problems. right now my computer sepcs are a e6750, 2 gigs and my 8800 gtx nvidia card, the computers a dell xps 720. Thanks
