Solution
First, here are a few troubleshooting steps to determine if the problem is with the PCIe card or the PC.
- Re-seat the PCIe card in the PCIe slot
- Try the PCIe card in another PCIe slot in the same computer
- Try the card in another computer
- Try a known working PCIe card in the PCIe slot that is having the problems
If the problem lies with the PC, there are a couple of possible steps that could help fix this issue.
- Update the firmware/BIOS for the computer motherboard. (This updated BIOS typically has to come from the motherboards manufacturer)
- Change BIOS settings for PCIe card from AUTO to GEN1 (Options typically are AUTO/GEN1/GEN2/GEN3)
