Both PCIe ports are not functioning properly.
Both PCIe ports are not functioning properly.
Hi. I have recently upgraded my whole system. It was working fine for a few weeks, then suddenly my GPU stopped outputting video. I swapped things around and tried the bottom PCIe slot and it worked. I was going to get the mobo checked in the next week. Then last night the same issue happened. The GPU definitely has power as the lights are all on. I tried plugging in my old 1070ti but this doesn't work either. I don't have any other GPUs to try but I don't think it's the GPU at this point. I can't check the bios because Ryzen doesn't have onboard graphics. I can't see any damage to the PCIe slots themselves but seeing as how it's both slots and they worked at first I don't think damage is the problem.
It might be your GPU or motherboard failing. Check what upgrades were made. Some boards can turn off specific PCIe features if particular hardware is present. Updated May 21, 2022 by An0maly_76 Added more details
I mean completely new components. The Asus TUF X570 gaming plus Ryzen 9 5900X, Asus TUF 3070TI OC Corsair RM750x functioned okay at first but eventually stopped working. I’m updating my BIOS and it seems several dozen revisions are outdated. I’ll let you know the outcome.
Solved! Your team was really helpful, though the solution turned out to be quite unusual. It seemed like forcing PCIe Gen 3 in the BIOS was necessary for the top slot. Apparently, it didn’t support Gen 4 even though the card is Gen 4. I think it worked in the lower slot for a while but gave up when trying to run a game because it’s an 8x slot. Now I’m thinking I’ll have to use my new 3070ti at reduced performance until it’s fixed. Thanks for your support!
