'Random DBA',
Been there, done that, have the T-shirt.
I had a Radeon card, wasn't HD. Switched to one that was but, still ATI. Blue screened, scared the crap outta me, thought, for a moment things were catastrophic... couldn't boot into anything & I have 3 OSs in this box & need everything for client support & more. Decided not to try another ATI card. I, ovbiously, managed to get the machine back on track. However I went w/ a Gigabyte GeForce210 instead & everything was/has been fine w/ it. Got an Exchange on the ATI card. Machine really did not like the ATI card, @ all!!
Maybe this anecdote helps
Regards,
Drew
