Hi guys, I recently got an used GTX 780 (http://www.gigabyte.com.au/Graphics-Card/GV-N780OC-3GD-rev-20#sp) from a friend of mine. It was working in his PC.
When I plug it in, it is detected by Device manager and works perfectly fine with the default/inbuilt windows VGA drivers. It however fails after driver installation.
I tried installing the drivers by 2 methods:
1. Installing drivers from NVIDIA download page(manual download and install)
Result: Installation starts normally, but mid-way the display goes black/monitors go idle and the GPU fan spins at 100%. It stays like this until i manually restart the PC. After reboot, the display goes gray-scale with reduced resolution and I get the error message "Display Driver failed to start". However, the PC doesn't restart (stable) nor the display goes black/turn-off.
2. Windows update (automatic driver installation via device manager)
Result: Windows boots up, i can see the welcome screen and the desktop. But after 2-3 secs the screen goes black, the monitor(s) go to idle/stand-by. The system is running normal (not crashing) with no display (I can hear windows sounds, etc.).
I have tried almost all the solutions suggested in multiple forum posts on the internet. Everytime i try to reinstall drivers, I always use DDU to clean the previous installation.
Any help is highly appreciated. If I missed any info, please let me know.
My PC specs are:
i7 3770
GTX 780
16 GB DDR3
ASUS p8h61-mx (mobo)
600W PSU (46A on 12V rail)
Windows 10 Pro 64bit
Additional info:
I can use my old GTX 650 ti without any problem. Also, if I remove the GTX 780, the iGPU works perfectly as well.
I have already tried the GPU with different PSU but to no avail.
I have tried fresh installation on a seperate SSD.
I have also tried fresh installation of Windows 7.
I havent checked the card in another PC (I dont have spare/secondary PC).
