Question Black Screen Max Fans Crash
Question Black Screen Max Fans Crash
I've been using this setup for several years, and recently the screen would go black while gaming, but sound still works and the GPU fans reach maximum speed. I've looked into it a lot, yet no clear solution has emerged. It seems the problem might be related to the 12vp cable and the PSU lacking a dedicated 12vp 8-pin port. The cable splits into three sections—two going into the PSU back panel and one into the GPU. I've become really frustrated; I barely use it anymore. Despite having built a PC for 15 years without issues, this has been the worst experience. I think it's connected to Nvidia's delayed release of the 12vp cable. When I received the parts list, it was still unclear what would work. Many people complained about damaged cables, PSUs that didn't deliver the needed voltage or power despite claims they could run the GPU. It's been the most irritating time ever trying to compile a parts list on the site. The whole situation over the past year has made me hesitant to buy another Nvidia PC. If anyone knows a reliable way to identify the cause, I'd really appreciate it. I might have to replace the case and PSU entirely and rebuild the system. It appears the PSU is likely the culprit, and I can't find a SFF PSU with a dedicated 12vp rail that would allow using a GPU power cable with one connector per side instead of the split design.
Here’s some useful advice if you’re looking to get people to assist you: list your key points clearly.
The PCIe to 12vhpwr adapter generally functions well. I haven’t encountered issues like yours that stem directly from the adapter. If the connector isn’t overheating and the card operates normally, it’s unlikely the PC will fail due to this part. But your power supply is pushing limits for a 4080, particularly since you also have a 13600k capable of drawing significant power. How long has your PSU been in use? An outdated 750W unit might struggle to meet the demands of your system.
Your mini tower may also be contributing to problems. While the mesh is effective against large dust, fine particles can still penetrate. Are you regularly cleaning the interior of the PC—especially the GPU heatsink and AIO radiator? What are your temperatures during gaming sessions?
Additionally, your small 120 mm AIO isn’t adequate for cooling the CPU. Even though the case is open, you still need to remove excess heat from the liquid. This radiator isn’t sufficient. As discussed earlier, what are your temperatures?
Lastly, what Nvidia drivers are you currently using?
Recent Nvidia drivers have been an issue for a year, regardless of the software used. For the CPU, I ran Cinebench under stress and consistently saw temperatures around 75, occasionally reaching 80 briefly. The GPU performed better, usually staying in the upper 60s to mid-70s. The power supply is quite old, matching the rest of the build; it worked fine for two years before this year’s random overheating during games. The AIO unit was the only one that fit comfortably, though I opted for a basic case fan instead. Temperatures have never exceeded 80. I regularly clean the tower and did so before writing this post. There are reports suggesting Intel drivers on the integrated CPU might be causing problems, with an error message appearing in Event Viewer when it fails to start. I’ve downloaded the latest driver for my Integrated HD 770, but it hasn’t resolved the issue yet. I’m also considering a sensor cable—possibly missing from the GPU’s cable—and upgraded to one with built-in temperature monitoring using two 8-pin PCIE cables instead of the old three. I’ll try this as well, though I’m not sure if updating drivers will fix it.
