Question White VGA light on Motherboard.

[VanityWasTaken]

Specs: intel i7-12700k, 3070 TI, 32 GBS OF DDR4 RAM, and a MSI pro z690-a motherboard.
I’ve had my NZXT prebuilt pc for around 3 years. I recently got a white light on the VGA spot for the motherboard. At first I could boot fine. Then I couldn’t boot at all. I would only get a black screen. I tried a different GPU from another system and it still didn’t work. I swapped the motherboard and got the same error. The only thing that is different is that this time after a while the white VGA will go away and then I can boot into BIOS/Windows. Bios is extremely laggy. If I go into windows and play for a while I have a chance that the pc will boot up under 180 seconds . I had it where the computer would boot with 16 GBS of ram and my graphics card. Whenever I get into windows after a minute or two my RAM stick lights will turn out. I think it’s an issue with the PSU because after a while of running the build it’ll work fine it just won’t run 32gbs of ram plus the GPU.
Update: I forgot to add this part. If I leave the unplugged all night I have a better chance of booting into bios without it lagging.

Sounds like a PSU or GPU, check the warranty for the system and the PSU see if you can get a replacement
