I've been getting a swiggly shadow line appearing behind things on my screen, like my cursor and the navigation bar on vBulletin boards. I upgraded my GPU fan to the Arctic Cooling Rev. 2 for the 6800GT and added 3 Cooler Master 80MM fans to my PC. And, I cleaned the other 3 existing case fans & CPU fan/heatsink, but it still happens. Right now, I'm using a big home fan to cool my PC w/ the side panel off. The swiggly shadows seem to be gone at this point. My temperatures according to EVERST Home Edition 2.2: Mobo: 21C CPU: 20C GPU: 37C GPU Ambient: 30C Without the big fan, my Ambient level would rise by 8 - 9, my CPU goes up to 25, 26, and GPU is at about 40 - 45. Can someone please help me? And if any more upgrades are necessary, I'd like to spend as less as possible. With those 4 fan upgrades recently, I've already spent 50 bucks. Thanks for all the help in advanced.
