Question How to fix my motherboard's VGA light coming on after a forced shutdown ?

[Luccerton]

Greetings,

Yesterday I had a forced shutdown on my pc because of a power outage in my street. Ever since then I have this weird thing that my my PC will not boot and shows me a VGA error light on my motherboard. If I remove the GPU, the light disappears and the system runs normal again but obviously on the CPU integrated graphics. The weird part is, that when I leave my GPU in the system even though nothing posts all leds are on and the fans spin. The system even generates idle heat.

Specs:
MOBO: MSI PRO B650-P WIFI
RAM: Corsair DDR5 Vengeance RGB 2x16GB 5600
SSD: Samsung 980 PRO 2TB M.2 SSD
CPU: AMD Ryzen 9 7900X
GPU: PowerColor Radeon RX 7900 XTX HellHound
PSU: be quiet! System Power 10 850W PSU / PC (Gold certified)


What ive tried to fix the issue:

• CMOS reset
• Reseating/switching of ram positions
• Removing a ram stick.
• Removing a ram stick and changing to new position.
• Remove SSD/M1drives.
• Checked for damage to the GPU
• Reseated the GPU
• Try diffrent PCI_E Lanes.
• Remove GPU --> system works now with integrated graphics.
• Remove drivers, install new latest drivers.
• Check BIOS, Updated BIOS.
• Put back GPU --> VGA Light again.
• Reseat every component in the system. Still the stupid light.

I have no idea what I can try next. Today I'll go to my brother and put my GPU in his system to see if it still works.

How do I fix this?

Welcome to the forums, newcomer!

If the system works without the discrete GPU, you either have;
1| a PSU that's incapable of delivering power to the entire system
or
2| your GPU is conked out
or
3| your motherboard's BIOS is partially corrupt.

For
#1, source(borrow, not buy) a higher wattage, reliably built PSU from a friend or neighbor and see if that resolves the issue.

#2, drop the GPU into another known working build with more than ample power for the entire rig and GPU, and see if the issue persists.

#3, reflash the BIOS with the latest BIOS version and then try the discrete GPU in your system.

Remove GPU --> system works now with integrated graphics.
Remove drivers, install new latest drivers.
Check BIOS, Updated BIOS.
Put back GPU --> VGA Light again.

Dead GPU.

Buy a new GPU. Also, to avoid further component damage due to power loss, buy an UPS as well. Preferably line-interactive topology, true/pure sine wave output.
I can tell more about UPS if you like.

Oh, your PSU is mediocre quality and can be the reason behind why your GPU died. I'd buy new, good/great quality PSU as well, just to avoid the Be Quiet! PSU killing other hardware next time (e.g MoBo).
Good PSUs to go for, are: Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, Super Flower Leadex Gold/Platinum/Titanium.
