Display goes black and cooling reaches maximum speed.
Hey there, curious user. I’ve noticed some odd behavior after swapping out my GPU. It seems the issue might be tied to the graphics card itself. I’m reaching out for more insights from experienced folks here. The problem involves random blackouts where both monitors go dark and fans crank up to 100%. It can happen right after turning on the PC, sometimes after hours of inactivity, and other times during gaming sessions. Usually, it doesn’t last all day even when the system stays on under heavy load or idle. I’ve tried a few fixes: adjusting GPU power settings to 90%, 80%, 75% and 65%, updating the GPU driver, upgrading to the latest Windows 10, and checking BIOS updates. I’m also considering testing the GPU on another machine, updating motherboard firmware, and replacing thermal pads. PC specs: Intel Core i7-8700K, Aorus Z370, RGB PRO RAM, RTX 4090, ASUS TUF case, Corsair HX850i PSU, and a 1TB SSD. Some threads I found online discuss similar issues: https://forums.
I've encountered the same issue before. Through research, calls with Nvidia and Asus, and forum troubleshooting, I might have discovered a solution. However, the result hasn't been favorable—it seems the motherboard or GPU is likely faulty. I've ordered a replacement 4070ti, which should arrive in two days. If you'd like, I can update here about whether the fix worked or not.
Sure, just let me know when you're ready. In the meantime, please remove the 12v 40 series splitter from your GPU and examine it for any damage. Check for broken or melted pins, clean any dust, and ensure it's fully seated in the GPU. It would be useful if you could share a photo of the splitter cable.
Really, I was worried about that. It seems I’ll have to get rid of it. I checked it a few weeks back—no broken, melted, or dusty parts. The 12v splitter was brand new and unused. I also made sure it’s fully plugged in (just a quick click and extra push). It’s been about 36 hours with no crashes, even with continuous folding. I’ll share a photo as soon as it fails next time.
It seems the system becomes unstable when it cools down. Combining folding and gaming works well, but restarting the PC and starting a cold session often causes crashes. Stopping folding also leads to instability, especially during gaming sessions with spikes in usage.
