Before you call a GPU dead, unstable, or “a driver problem,” work through this checklist and post the results. It saves time and makes the diagnosis sharper.

1. Confirm the failure state

• No signal before the OS loads.
• Black screen only after the driver initializes.
• System hard-freeze under load.
• Driver reset, TDR, or recoverable crash.
• Reboot loop, artifacting, or only one display failing.

2. Record the exact hardware path

• GPU model and board partner.
• CPU, motherboard, BIOS version, RAM, PSU model, case, and cooling.
• Monitor model, cable type, adapter or dock if any, and which GPU port is in use.

3. Check the obvious before chasing ghosts

• Reseat the GPU and both ends of the display cable.
• Use a different known-good cable and a different port.
• Verify every PCIe power lead is fully seated and not split in a way the PSU vendor warns against.
• Remove risers, adapters, and unnecessary USB devices for first-pass testing.

4. Separate firmware, driver, and hardware layers

• If there is no image in firmware setup or during POST, that points away from a pure driver issue.
• If the fault starts only when the OS loads the display driver, note the exact driver branch and version.
• If the system fails only under load, log hotspot temperature, fan speed, power draw, and PSU behavior.

5. Reduce variables

• Revert overclocks, undervolts, custom fan curves, and unusual PCIe settings.
• Test one monitor at stock refresh rate.
• If possible, test the card in another known-good system or test a known-good card in the same system.

6. Include evidence

• Event Viewer or Linux journal entries.
• Photos of artifacts or board damage.
• HWiNFO, GPU-Z, or sensor logs.
• Exact crash messages.

A good troubleshooting thread says what failed, under what conditions, and what changed after each test.
