FurMark Black Screen: Safe Recovery Steps
Quick answer
Stop the stress test, let the system cool and restore known-good GPU settings. Repeatedly forcing the same failure is not a safe diagnostic plan.
What should I do after a black screen in FurMark?
Stop the stress test, let the system cool and restore known-good GPU settings. Repeatedly forcing the same failure is not a safe diagnostic plan.
Prepare a controlled Windows test
FurMark is a deliberately demanding graphics workload and should not be treated as a routine background task. Make sure the computer has adequate cooling and normal airflow, close other graphics-heavy programs, and locate the manufacturer’s published operating limits for your exact graphics card. If a system already has cooling problems, do not begin the test.
If Windows recovers, record the display-driver event and exact test preset. Reset overclocks and undervolts. Check approved power connections, cooling and the current graphics driver before any limited follow-up.
Keep conditions consistent
If the monitor loses signal but Windows continues responding, review the display path. If the PC reboots or powers off, also consider system-level power and hardware issues.
For repeatable results, preserve the FurMark major version, graphics API, preset, resolution, anti-aliasing mode, driver version and Windows power configuration. Keep a record of whether the GPU started cool or had just completed another workload. Changing several of these at once makes a before-and-after comparison unreliable.
Understand the results
Do not treat a crash during an extreme workload as conclusive evidence of PSU failure. Test stable everyday workloads and seek qualified help for recurring shutdowns.
Observe the trend of temperatures and clocks rather than one peak value. A completed run demonstrates how the particular device handled that particular test; it does not certify the GPU, power supply, memory or overall PC. If performance varies, compare readings from the same system and consider a second, less intense real-world workload.
Stop conditions and next steps
End the run immediately if cooling no longer appears effective, the screen displays corruption, the graphics driver repeatedly resets, Windows freezes, or temperatures approach the manufacturer’s stated limit. Do not disable thermal or electrical protections. Allow cooling time before troubleshooting and avoid repeating crashes just to reproduce a result.

Frequently asked questions
What should I do after a black screen in FurMark?
Stop the stress test, let the system cool and restore known-good GPU settings. Repeatedly forcing the same failure is not a safe diagnostic plan.
Does passing this test guarantee that my GPU is healthy?
No. A passing stress test cannot rule out problems under other APIs, games or application workloads. Combine supervised measurements with normal usage and hardware documentation.
Should I maximize the power limit to improve the result?
No. Follow the hardware manufacturer’s published limits and do not defeat safety protections to obtain a higher benchmark score.
