Black screen with fans increasing to full power?
Black screen with fans increasing to full power?
I've been experiencing this issue for several months. It began sporadically, perhaps once every month or two, and has increased to several times a day now. It occurs while idle and during random gaming sessions.
System details:
MBD: MSI MAG B650 WiFi
CPU: Ryzen 7 7800X3D
GPU: 4090 Suprim X
PSU: NZXT C1200
RAM: Corsair Vengeance
I usually hear a disconnected noise and my audio sometimes plays intermittently. The event viewer doesn't display anything. I tried force crashing with a keyboard, but once it didn't produce a dump file. On another occasion, I had a dump file, though I'm unsure what to look for. Occasionally the computer restarts on its own after these events and created a dump file indicating nlddmkm.sys crashed. In the event viewer, I saw a gameinput error, but I've resolved that issue and the crashes persist. A memory check showed no problems. During one crash, a log recorded that GPU data stopped being recorded, with graphs turning into flat lines. Upon reviewing the graphs, I noticed the integrated graphics had unstable power usage even when nothing was connected. Disabling the integrated graphics removed the load, suggesting it might be the cause.
I attempted multiple times to unplug the PCIe and power connections and reconnect them, but it didn't resolve the issue. Removing the 12VHPWR cable from the PSU and reinserting it fixed my problem. It seems this is likely related to a C1200PSU from NZXT. Perhaps one of the sense pins is faulty or disconnected.

Yes, they produce server power supplies with the 12VHPWR specification.
