My 8800GTX (which has been in regular gaming use for about 3.5 years now) seems to be dying. While playing starcraft 2 a few days ago I got a load of pink artifacts all over the screen for a few seconds, followed by a black screen, and then a system lock up. I rebooted the PC, got back into the game OK, but the same thing happened during that new game. Now I can barely use the PC. I can get into windows occasionally (when I can windows is usually using the Standard VGA driver), but almost instantly there are pink (or sometimes green) artifacts appearing on screen in no particular place. Opening or navigating in an explorer window while like this results in a long pause, followed by a black screen, then the picture reapperaing with the window open/ the new location. I have been trying to get my PC up and running again to no avail. It seems to memtest OK (although I haven't run it for a long time), but I have even seen the artifacts over the BIOS screen leading me to suspect a possible thermal problem. Putting the card in another PC with another screen gives the same problem. I have given it a clean with an air compressor, and a lot of caked thermal paste came out. As far as I can see it is the excess which was already on the card (stock thermal paste) which has been blown off leaving the useful paste intact. I was thinking of giving the card a fresh application of thermal paste, but I don't have any new thermal pads to hand and only have Arctic Cooling MX-5 paste. Is this a sensible step, or is it probably a more severe problem? Has anybody encountered a similar problem or has any better ideas? The card is an OEM job so no warranty... It looks like the first result here. I've never overclocked it. 32-bit Windows Vista Intel E8400 2x 1Gb Crucial Ballistix DDR2-800 Asus P5K-Premium Wifi-AP(3.0GHz) Corsair HX620W Freezer 7 Pro Seagate 500Gb PS: I had planning to build a new rig when I hit the 4 year mark, but being revision season now is not really the right time for an emergency build. I had also planned on passing the current rig to my sisters (an allow them to play the Sims 2 at more than 10fps!) so getting this working again would be nice... This laptop really stinks!!
