Issue- I have full power to my graphics card, the fans are spinning and they RGB lights light up but yet I do not get a signal in the first PCI slot. The graphics work in the 2nd PCI slot but I get lower performance. Please help and thank you.
 
Solution
First, are bios, firmware, drivers, and software up to date for all your components, particularly the mobo and gpu? I would start there. There’s a similar question on the forums here and someone suggested it could be damaged PCIE pin(s) either in the card or the mobo, and the damage could be visible (physical) or not (internal/electrical). Do you have another card to test in the slot? If another x16 card works there, then the problem is with the card. If the second card behaves the same, then the problem is in the mobo. If the damage is in the card, it could be on a pin(s) that are not used in the x8 slot.

Of course, it could be as simple as some dust or lint in the PCIE socket in slot 1.
