Motherboard White VGA indicator on the motherboard
I have received the latest components and after setup, the system shows a white light on VGA. The motherboard is an ASUS RUF Gaming B760 with the I7-14700KF CPU, RTX 3700 GPU, and a Corsair TX 750 PSU. I’ve tried various fixes online: clearing CMOS, swapping battery, testing RAM, changing cables, adjusting video connections, and ensuring monitors are powered on. Everything functioned normally before the changes, so I’m confident the GPU is working. The motherboard supports both 8-pin and 4-pin CPU power connectors, but my PSU lacks a 4-pin cable. Should I replace the PSU or consider returning it as non-functional?
The four pin CPU cable isn't necessary unless you're doing extreme overclocking with LN2. If the VGA light is on, it suggests the system can't detect the GPU. Assuming the GPU works, the next steps would be checking the motherboard's PCIe socket or the CPU's PCIe lanes for issues like bent pins. I'd also look for dust or debris in the GPU's PCIe slot. If everything seems okay there, I'd test with another GPU to confirm.
Ensure all power cables match your specific PSU; using mismatched cables may cause problems. GPU placement: reinsert it firmly in its PCIe slot and confirm the cable is locked in. RAM installation: check that sticks are correctly seated. Monitor setup: make sure the monitor connects to the GPU, not the main board. Component checks: test each part separately to spot issues. Replacement options: return or swap faulty parts, particularly if covered under warranty.
You've checked everything thoroughly—cleaned slots, used a borrowed GPU, tested all RAM settings, removed the CPU for inspection. The issue persists, but the shop suggested a BIOS update might help. They also mentioned shipping and service times make it less appealing. It seems updating the BIOS could be a viable solution, though timing and logistics matter. Consider reaching out directly to confirm their timeline and see if they can expedite the process.
