My specs are in my signature.

I'm running Windows 8.1

I was running a program called "cudaminer," a litecoin mining program written in CUDA to bolster performance on NVidia cards--from really sucky to just sucky)

Anyway, I was running this program with my graphics card at about 80%.

I read that I needed the CUDA library, so I downloaded the CUDA development kit and started install. Like an idiot, I failed to terminate the cudaminer program.

Also like an idiot, I failed to notice that the cuda kit would try to install the 320 driver. The screens went black for about 30-60 sec and then I got the BSOD with the smiley face.

When the machine rebooted, my BIOS was messed up, so I had to go in and reset my bios. When the machine booted up, it defaulted to my DVI monitor with the HDMI non-functional.

Since then, I have been unable to install any drivers. The Device manager does not see my card, nor does GPU-z.

I have shut down the computer completely, with and without unplugging, checked to see that my BIOS is current, popped the battery on my MB, and tried to install NVidia drivers 327.23, 331.65, 331.82 all to no avail.

Every time I attempt an installation, it makes it into the installing graphics driver and then defaults back to the menu with a list of what wasn't installed.

I am at a loss.
 
Solution
1) Use SYSTEM RESTORE to rollback prior to the problem, if a backup exists.

2) run MEMTEST to ensure your main memory isn't corrupted (I had issues installing NVidia drivers and it turned out to be defective DDR3 memory). www.memtest.org (one complete cycle, about 30min for 8GB).

I have further advice if needed.

As Tennessee Ernie Ford used to say (back in the day), "Bless your pea-pickin' heart."

After 6 hours of panic and mahem, just "RESTORE" and the problem is gone.

Thanks a bunch, photonboy!!!
