playing DDO online this am , game closed PC restarted. I restarted safe mode, uninstalled video driver,re-installed, nothing. uninstalled game, reinstalled , nothing. PC boots,Windows loads ,go to BSOD scrambled. My guess is video card memory died , Saphire ATI radeon 4850 1G
Uh, yeah that doesn't look good, and the fact thatit even shows up on the BSOD says that a dead card is quite possible.
There's a couple other possibilities though those are unlikely. Its also possible that you bumped the machine and the contact between the motherboard and card got a bit misplaced. happened to me a number of times with my hard drives
