I have an MacPro 5,1 with EVGA GTX 680 Mac EDITION, with two SSD drives
1 SSD Mac OS X 10.8.5
1 SSD Windows 8.1
Using BootCamp5.1.5621 drivers on the MacPro.
DAY1
Put in the new Card OS X Booted Great, tested everything as expected. Then I booted over to Windows 8.1 Screen resolution came in at 640x480, so I rebooted. The screen was completely black on reboot.
DAY2
Read that Windows 8.1 was using old or expired drivers in its automatic driver updates, I safe-booted and disabled
like here
rebooted, still black screen.
DAY3 and DAY4
STEP1.
Safe Booted and got an app called DDU
I uninstalled ALL drivers for windows 8.1 I rebooted and under DEVICE MANAGER it saw my video card as the Generic Microsoft Video driver or whatever it was.
I then installed the EVGA drivers according to the EVGA website.
I tried Driver 335.23
During install SCREEN FLASHES BLACK, then BLACK FOREVER.
WENT BACK TO STEP1.
I tried Beta Driver 334.67
During install SCREEN FLASHES BLACK, then BLACK FOREVER.
WENT BACK TO STEP1.
I tried GEFORCE DRIVERS 334.89, 326.01, 327.23 and 335.23.
During install SCREEN FLASHES BLACK, then BLACK FOREVER.
WENT BACK TO STEP1.
DAY5
Safe Booted and got an app called DDU
I uninstalled ALL drivers for windows 8.1 I rebooted and under DEVICE MANAGER it saw my video card as the Generic Microsoft Video driver or whatever it was.
Then I went back to the BOOTCAMP folder, found the NVIDIA drivers for the video card and it ERRORS during the installation.
