Hello everyone, new to posting here and i would appricate anyone help. So a month ago i built a new PC with follwoing spec : MSI B550-A pro Ryzen 5700x Corsair vengance LPX 3200mhz (16gbx2) Corsair rm750x 1TB Crucial P1 NVMe M.2 2280 PCIe 3.0 x4 ASrock phantom gaming RX6800 So everything was working perfectly fine , i got a new PCIe 4.0 ssd and i wanted to instal it . so i took out my GPU so i can seat the new nvme in the PCIe 4.0 slot and bring the old one to the PCIe.3.0 slot. i put everything together and the PC refused to post , and the debug led on the mobo shows vga error i tried reseating gpu , using another PCIe slot , cleaing . nothing seemed to help i borrowed a freind GPU and it did not work in my system (only tired the top PCIe slot) , and my GPU did work in anohter system i ruled its a Mobo issues next day i pick up another mobo (Asus Prime B550-Plus) and the intersting thing here , the GPU DID NOT WORK on the man picie slot but it DID WORK on the secandary one . i tired changing the slot from auto to both 3.0 and 4.0 and nothing seemed to help. any help on how to go about digonising the issues would be highly appricated , im just so stumped and over all panicking. Could it be somehow the CPU ? Thanks in advance
For this matter, I recommend upgrading or updating the BIOS first among the initial troubleshooting steps.
Could the system start if you reset it to its original settings, which might indicate a problem with the new SSD?
You were using the MSI B550 board with the bottom PCIe slot (PCI_E2). Your manual indicates that this slot is disabled when you're running two NVMe drives.
I already knew about that before. After several tests, it turned out the CPU was the problem. After switching to another CPU, everything functioned properly. It looks like there was an issue specifically with the CPU and the top PCIe port.
