Im having a problem with my computer which i have had since day one. While i am playing WOW or some other games or even when im on the internet (mostly happens when playing games) my computer freezes then restarts. When i talked to techinal support they said it could be the graphics card cause of some windows vista thing and high end cards. So i replaced it and downloaded some fixes and it seemed to work for a couple of weeks and then it started doing it again. Does anyone know what it might be and how i can fix it.
