Im sure this is nothing new for you computer guros, but for the average gamer like me....Take the time every couple months to open your tower and clean your CPU...Last night I opened it up and could have filled a large glass with the amount of dust I found...Most was in the fan of my video card, which was causing the card to overheat...After cleaning my card and guts inside the tower I find my machine is running 100%'s better...specially in GV mode....so take the time and give it a look, it may help
