i have a dell 1420 laptop... with 8400M gs graphic card while playing fifa09, screen went wired colors, then it just restarted. took a couple of reboots to even get the dell logo to come up. it load up, i started watching .avi file after like 45m it crash again. wired colors.. sound was still going but then after a while it just restarted. took alot more attempts to get the dell logo to come up. at first i thought it was the driver, so i updated that when i finally got vista back up. but after restart and going back to watch the movie it crashed again. i thought it may have been over heating.. but core temp dont go above 50C. any ideas what could be wrong? it seems to me that the graphic card is destroyed but then how is it able to run windows aero. ps. im using the laptop right now to type this.. it doesnt seem unstable under vista but loses it when opening a video file.
