Fantastic. Nothing was wrong for a month, when yesterday my screen went black. This stupid crash again. I had to reinstall the Vcard drivers to get rid of the funny dizzy dots everywhere. It worked for a while, then it crased when I watched a movie. Reinstalled again, then it crashed when I was in the main menu of a game. The funny thing is, not even Ubuntu would work after such a crash. So I installed the drivers by the win updater, and as I was typing this message I got 2x "display driver stopped responding..." errors. Damnit!
Won't hurt to make sure you heat sink is free of dust.
