I've been having the same problem with an RTX 3070—I haven't noticed any hitches during normal functioning, but I also haven't used it in VR. What specs do you have? Mine are:
CPU: AMD Ryzen 7 3700X 8-Core Processor
MB: B550-A PRO (MS-7C56)
PSU: Thermaltake Toughpower GF1 750W 80+ Gold
GPU: RTX 3070
RAM: 4x8gb DDR4 (2x OLOy 8GB 288-Pin DDR4 3000, 2x GeIL EVO POTENZA AMD 8GB 288-Pin DDR4 2400)
I don't have a solution for you—I wish I did!—but I think I'm a little further down the same road, so I can maybe still be helpful. I had this problem for the first time ~2 weeks ago—after a day of trying different things, my first reseat attempt seemed to fix the problem. The problem came back again 2 days ago, spent another day trying different things, then yesterday morning I tried a power drain first thing (power computer off, unplug, hold power button for 2 minutes), and was able to immediately boot and install drivers no problem right afterward. Last night when I shut my computer down, I got the bad boot/prompt to repair again, and power draining does not fix it this time.
Here are things I have tried that have not had any noticeable effect:
- Updating BIOS.
- Reinstalling Windows.
- Using old NVIDIA drivers (can only go back to 457, get an 'incompatible Windows version' error otherwise).
- Rolling back Windows feature/quality updates.
- Replacing my new PSU with my old PSU (had installed a new PSU 5 days before this happened for the first time).
- System restoring to old checkpoint.
- Reinstalling chipset drivers.
- Changing PCIe slot to use Gen3 in BIOS.
I think the above list—plus reseating the GPU + power draining—are all the things I've come across to try in, now, days of looking through old forum posts, talking to NVIDIA support, etc. They didn't work for me, but you should try them.
Actually, just as I was typing this, I successfully installed drivers through a new method: I'd been using a DisplayPort -> miniDP cable to connect my GPU to my monitor for every previous attempt. I just switched to an HDMI cable and was able to install my drivers first try. No idea if there's a relationship here, no idea if I'll crash again in 10 minutes, but thought that might be worth sharing if you're using DP.
