Graphics card not working, sometimes

metalmania80 · October 24, 2023

Hey everyone, hope someone can help me troubleshoot my pc issues. I've been having issues with my pc since I moved.

What happens is when I boot my pc everything starts up normally, but sometimes the GPU shuts off the LEDs, ramps the fans up, and my mobo shows a VGA issue. For a short while i was able to hard power down my pc, unplug all DP cables out of the GPU and it would boot fine. Sometimes that doesn't work and it seems like it just doesn't work for days on end until it randomly decides to fix itself. Another weird thing my pc does on boot is the troubleshooting LEDs go from Red(cpu) to Orange (ram) to Red(Cpu) to Orange (ram) then to white(vga) and stays there. If it's going to boot properly it will switch from white to green after 2-3 seconds. This is making me think Motherboard, especially since this mobo has moved 7 times in it's lifetime.

Specs:

CPU: AMD Ryzen 7 3700x

Motherboard: Asus b450-f Gaming

Bios version: 2801

GPU: EVGA 2080 ti hybrid cooled

RAM: 16 GB Corsair Vengeance Pro 3200Mhz

PSU: Corsair RM850x

Boot drive: Samsung 750 Evo SSD

I've updated drivers for nvidia and made sure that windows was fully up to date, no changes with those updates.

I've gone ahead and tried re-applying thermal paste thinking it was a thermals issue but that has fixed nothing.

I tried the 2080ti in my roommates computer and sometimes it works fine, and sometimes it doesn't output any display. All while his 1080 works fine every time in my computer.

My next thought was a PSU issue so I upgraded my PSU from an EVGA 750w to the 850w I currently have installed (the 750w seems to have fixed some issues my roommate was having with crashes with his computer system.)

The most recent time this happened I have swapped GPU's with a friend who is currently using my 2080ti perfectly fine for him (in another city), while I use his AMD 6500xt working perfectly fine.

My next thought is maybe a power issue through the PCI-e slot. But I don't have any GPU's available to test that are as power hungry as that 2080ti.

While making this post I also realized my mobo Bios is out of date quite a bit, so maybe that?

My only other thought would be to get a UPS as a power buffer from the wall to my pc as I've heard of 'dirty power' before. But that's honestly pulling random ideas out of my ass.

Any help or ideas to test when I can is greatly appreciated!
