World of Warcraft BSOD X(?

Ok, I've gotten tired of free mmos so I thought about starting a p2p like WoW. So I downloaded the 10 day free trial and tried it out. It worked fine for around 10 min or so but then it crashed on me and I got the blue screen of death. The Blizzard wow site says that my graphics card, an Intel GMA 3100, is supported and my computer has 4 gigs of ram so I thought it would run WoW fine, but it doesn't X( So does anyone know what the issue is?
