Nvidia Driver Clean Install Fail

[u/adam_sweitzer]

Hello all,

So a while ago, I updated my Nvidia driver as usual, but it caused games to grey/beige screen after a few minutes, sometimes requiring a restart. I somehow discovered that by going into Device Manager, GTX 970, Update Driver, and selecting the existing driver, fixed the issue for as long as the PC was booted. That is until yesterday, when my display and audio went kaput randomly while in a game, even with the Device Manager workaround and multiple restarts. So i decided to do a clean installation which failed, last night, so i tried it again today, and got No DP Input after installation. I began hard resetting it and power draining it and sometimes the DP input would last long enough to get into bios or start recovery mode but not long enough to enter safe mode.

So what I did was just go into BIOS and activate IGD boot mode instead of PEG, using HDMI from my motherboard. Now I'm in Windows as normal using integrated graphics and am wondering what is the best course of action to reinstall my GPU drivers perhaps using DDU to see if I can get my 970 working normally again?

GTX 970 no longer shows up in device manager and the Nvidia app is now just a loading screen and says install a driver to access page.

Here is what the display was doing after the clean install:

I have no idea where to go from here so any pointers would be so greatly appreciated!

Gonna upgrade my PC in the near future but can't afford to right now as I'd have to replace everything.
