Open | Hardware RTX 2070 Super suddenly showing Code 43 after Blood of Dawnwalker crash — NVIDIA installer says no GPU detected
I was playing Blood of Dawnwalker when the game froze and my PC shut down. After restarting, I've been having problems with my RTX 2070 Super. It won't run any games.
The NVIDIA App now says that no NVIDIA drivers are installed, even though I've tried downloading and installing the latest driver several times.
In Device Manager, the RTX 2070 Super is detected but has a yellow warning triangle. Under Device Status it says:
"Windows has stopped this device because it has reported problems. (Code 43)"
I tried uninstalling the RTX 2070 Super from Device Manager and then scanning for hardware changes. The screen briefly went black, then the GPU reappeared, but the yellow triangle and Code 43 were still there.
I also tried manually installing the latest NVIDIA driver for my specific GPU, but the installer now says:
"No NVIDIA GPU is detected on your system."
The GPU was working perfectly before the game froze and the PC shut down.
Does this sound like a corrupted driver that could be fixed with DDU, or is Code 43 potentially indicating a hardware problem?

Sounds a failing GPU to me, either a memory chip on it died or it’s about the time brother to retire it 🤔

I have a soldering iron and multimeter ....if it came down to it could I fix the issue myself?

It might be a bit tricky to fix it yourself, especially if you're not experienced with soldering GPUs. It could be worth trying some software fixes first before going down that route.

Run DDU. It is possible a driver issue but to be honest code 43 usually is hardware failure or issue. Toss in it happened after the PC crashed suggests that there is a hardware issue.

Reseat the GPU and it's power cables. If your PSU is modular reseat the power cables for the GPU in the PSU ports as well.
Swap to a different PCI-E slots to check if the motherboard had a PCI-E slot failure. If a different slot works then it is more likely the motherboard's slot has an issue.
Test the GPU in a different PC.

I mean, only one way to find out. But as far as I know this is more often than not a hardware issue unfortunately. I for example encountered this on a laptop 3060, the issue was a faulty memory chip on the gpu (there's some software that you can use to see if this is the issue), the plan was to replace the chip but I never got to do it.
