Display problems with your graphics card.
Display problems with your graphics card.
Hello, I was assembling a custom gaming PC and used a PCIe riser to link the GPU to the motherboard. When I tried to boot up, the VGA light stayed on but nothing appeared on my screen. Later, when connecting the riser to another PC, the same problem occurred. Since both the PCIe slot and the GPU are not securely fastened, I’m wondering if I need to secure them for the GPU to function properly. This is confusing because I’ve never worked with a PCIe riser before.
They don’t have to lock the card or the riser in place for it to function. The PC can hang from the ceiling with the card floating freely, provided all parts—card, cable, and the PCIe slot on the motherboard—are properly connected. (In this case, good contact is usually short-lived.) Your past issues suggest the riser cable might be damaged or the BIOS settings for that PCIe slot could be incorrect.
GPU, Mobo, and Riser specifics can guide you without full details. My best guess is you likely have a PCIe3 riser and are attempting to pair it with a PCIe4 GPU. If true, you should either rely on built-in graphics or connect the GPU directly long enough to enter BIOS and adjust the PCIe slot to enable PCIe3 mode for the riser. Risers don’t support forward/backward compatibility like the cards or slots do.
