I have a 3070, ryzen 7 5800x, I had a b550 tomahawk, PSU 600W. I came home from work one day and I had code 43 on my gpu.

I've switched out my gpu, got the error on that one too. I switched pcie slots and it works on the second one. I got a NEW motherboard. Code 43 still pops up. I have ran DDU, changed bios to default, updated bios, rolled back windows, still code 43. I know it's not gpu because it still happened on my other gpu, and it works on pci slot 2.

Any fixes? I'm all out of ideas at this point.
