Question Display Issues with GPU - Need Help Diagnosing

[microwave1025]

Hello everyone,

I'm facing a frustrating problem with my PC and I'm hoping someone here can help me out.

Issue:A couple of days ago, my screen went black while playing CS2, but the sound kept playing and all LEDs and fans were still running. After shutting down and restarting, I got a "No input detected" message.

Steps I’ve Taken:

1. Switched to Integrated Graphics: I connected my HDMI to the motherboard's port (using the integrated graphics) while leaving the GPU in place. This led to frequent blackouts and restarts.
2. Removed the GPU: With the GPU removed, the system worked fine.
3. Driver Uninstallation and Reinstallation:
   • Used DDU to uninstall the NVIDIA drivers.
   • Performed a clean installation of NVIDIA drivers.
4. Checked BIOS: When I rebooted into BIOS with the HDMI connected to the motherboard and the GPU still installed, the GPU wasn't detected.
5. Reseated the GPU: I reseated the GPU and repeatedly tried uninstalling and reinstalling the drivers. Sometimes, the GPU was detected, and I could use the PC for a few hours before it crashed again.

Observed Problems:

• Total blackout
• Total green screen
• Total bright purple screen

When the GPU was detected, I tried shaking it slightly to check for loose PCIe slots or improper seating, but there was no effect.

Current Situation:I'm currently using my PC with integrated graphics, and the GPU is removed.

Questions:​

1. Is this more likely a GPU failure or a motherboard issue?
2. Are there any additional troubleshooting steps I should take?
3. How can I definitively determine if the issue lies with the GPU or the motherboard?

Any help or suggestions would be greatly appreciated. Thanks in advance!

What the sys specs really are?

Is this more likely a GPU failure or a motherboard issue?

Most likely GPU gave up a ghost. If it were MoBo issue, you couldn't boot to OS even.

Are there any additional troubleshooting steps I should take?

How can I definitively determine if the issue lies with the GPU or the motherboard?

Try with 2nd, known to work GPU. With this, you can rule out MoBo PCI-E x16 slot being the issue.
