Cool GTX
My first guess, that your GPU OC software was running & hamstrung the Nvidia driver install (known issue)
No idea what power mode your OS is set to
Nvidia Control settings .... what did you change from default?
The NV control panel is at default, and my system is at the ultimate performance plan. I have DDUed to no avail, but I will try with a stock and untweaked OS without any OC software once I am home
IF other GPUs work correctly in your PC ... then probably not an OS issue ..... test in Safe Mode ... kills all the background stuff is an easy thing to try
Disable OC software for GPU, set the option for the OC auto start on reboot = Off -- then when you reboot OC software does not start
Then while holding shift key down --> shut down PC --Holding shift key -- until All power is off = Clear Windows last good start file; as you want Windows to do a driver & hardware inventory
- Also, make sure in MB BIOS that the Fast Boot is --> Off you want the MB to take inventory
Then go off line, remove old driver DDU if you want & then install the new Nvidia driver & set Nvidia CP to performance mode & see if that helps
--> What other software is running in the background?
Clean OS install is the last option & might not be needed
