I received a 260 last night. Prior to install it, I removed the drivers and cleaned them in Safe Mode. Then I proceeded to install the card, and the rig booted fine the first time around. Installed the latest drivers, restarted... then it hung up on me. Shutdown - restart, hangs again exactly at 59 seconds starting from the Welcome screen. Did this to me 3 times.
How can I find out which driver causes the issue? And why now, when the rig is unmodified software / hardware-wise (aside from the added 260)? Side note, Device Manager shows dual 260s, no yellow (!) tag.
edit: 260 #2's Device Manager Resource tab (while in Safe Mode) shows "This device ins't using any resources because it has a problem." Is this an IRQ problem? If so, how do I come about to resolve this? I never played with IRQs before.
I really hope it's not a dud card - though I did test it prior to wc'ing it...
Any ideas?
