PC doesn't post with GPU installed

felikesi · February 20, 2024

Hey everyone,

I've been trying to figure out what's been happening to my pc for the past several weeks.
This PC was upgraded in November 2022.

Spec List:

13700k
MSI Z690-A DDR4
Corsair Vengeance LPX (2 x 16 GB) DDR4-3600
Noctua NH-D15S
EVGA 2070 Super XC Ultra (from old build)
Corsair MP600 Pro XT
EVGA 650 G+ -> Corsair RMx 850 Shift
Dell S2522HG
LG 27GR95QE-B

My PC has been fine for over a year since I've upgraded, but one morning I tried to boot up and my GPU fans are at max speed and the mobo's VGA led is on. I didn't think too much of it at the time and just pressed the reset button on the case and it was able to boot fine.

After that every morning when I boot, I have to reset multiple times before the PC is able to post.

From looking at other forums and threads, I've tried:
- reset CMOS (removed cord from wall, removed battery, waited several minutes, reinstalled)
- removed peripherals

- installed GPU into other PCI slot

- upgraded my power supply from a 650 Watt to a 850 Watt

- reseated RAM, tried with 1 stick

Nothing appears to have helped.

I installed the GPU into another PC and it's works fine.
But PC is able to boot without a GPU installed.

Any ideas? Thanks in advance!
