Screen turns black during shutdown after heavy usage
Screen turns black during shutdown after heavy usage
Hi everyone! A few months ago I upgraded from a GTX 1080 to a RTX 3090 that I purchased used. Before switching to the new graphics card, everything was working perfectly. After the upgrade, I encountered a problem where the screen would go black instantly—no light at all, just no signal—right after the GPU changed its workload (like quitting a game or running a benchmark). Even with Furmark and CPU stress tests, everything ran smoothly. Temperatures stayed normal, maxing out around 77°C on the GPU.
So far I've tried a few things:
- With the compact case, a riser was needed; I changed the PCI-E version in BIOS because my card is a lower version.
- Updated the GPU using Inno3D’s REBAR tool to enable resizable BAR.
- Disabled turbo boost since the cooler wasn’t cooling enough.
- Ran MATS tests (5MB–50MB) and vulkan_memtest for nearly two hours—both passed without issues.
- The tool crashed immediately when I closed it with CTRL+C, but that didn’t affect the GPU itself.
- Reinstalled Windows 11 from scratch after some time with the new card installed.
My current setup:
- Case: Fractal Design Ridge Black
- Motherboard: MSI MEG Z690i mini-ITX
- PSU: Corsair SF750 (2018)
- GPU: Inno3D iChill X4 RTX 3090
- SSD: Samsung 980 Pro m.2 1TB
- CPU: Intel i7-13700K
- RAM: 64GB
I’m a bit unsure what to try next. My goal was to fix one memory channel so it could handle 20GB instead of 24GB. If anyone has suggestions, please let me know. Thanks in advance!
Did you test the previous versions and save the files for the 3090?
I understand, I didn't mention that before. I also reinstalled Windows 10 entirely from the beginning as part of my approach.
Consider removing the riser cable and placing the system in plain cardboard if needed. Possibly adjust the voltage on the 3090 chipset. If power issues arise, lowering the current might help. For heat concerns, reducing thermal output could assist. (Also, I think you could easily undervolt the CPU using MSI CPU Lite load mode—switched from mode 18 to 11.) Updated April 18, 2025 by leclod
I just had another crash while connecting the card directly into the PCI-E slot on the motherboard. It didn’t fail during the Vulkan memtest, so I thought it was a win and sent an email to Fractal Design asking for a newer PCI-E 4.0 riser for the case. After turning off both Furmark and the Vulkan memtest, the PC ran smoothly, but when I tried to submit that request, it crashed again. It seems the issue isn’t under heavy use—actually, it improves right after I stop using the GPU. Anyone have other ideas or should I assume the GPU is broken? I want to be sure it’s not a hardware problem.
I just tried it in an older version I had saved. I initially suspected the GPU was the problem, but now it's confirmed. The same behavior appeared during a new installation on another machine. Appreciate your feedback!
