I have been having this problem for the past few weeks. I recently got a new computer in April, and its awesome. I have been having troubles lately though. I play lots of games including Battlefield 2142, Supreme Commander and Company Of Heroes. I just recently noticed that my pc isnt performing as well (Being Glitchy in games), and I checked the air coming out of my PC and it seems to be very hot. I dont see any dust though. My important specs: -Intel C2D E6600 Water Cooled -Nvidia Geforce 8800 GTX Stock Cooled I dont know why its doing this, but some help would be nice.
