System freezes with a black display and maximum fan speed.
Hello, I recently acquired a 4090 FE and have encountered some unpredictable crashes. The machine ceases to display on all screens, showing a no-signal alert, while the GPU lights dim and all fans increase to maximum—even those on the GPU. When playing games, sound effects continue to play during the crash but no new ones appear. The only solution is to press and hold the power button or force shutdown. This occurs sporadically: sometimes every hour, other times for 6 to 10 hours in a row. Previously, I could trigger it consistently by running BG3 while watching a YouTube video, but after that, it stopped happening. It can happen while gaming, when idle on the desktop, or during light web browsing. I’m confident it’s not related to the power supply since the system still functions normally otherwise. Also, the 4090 draws only marginally more power than the previous card, making a power issue unlikely. I suspect the issue isn’t with the motherboard, CPU, RAM, etc.—I reinstalled the old card two weeks ago and everything worked fine. All testing has been conducted under normal conditions: stock clock speeds, power limits, latest BIOS/firmware, drivers, and Windows updates. I’m using DDU in safe mode during swaps and temperatures remain within typical ranges (GPU load 50%, CPU 75%, GPU hotspot 70°C). The Windows Event Viewer shows only the expected power loss when holding the button. I contacted NVIDIA, who agreed to handle the return. They sent the new card today; it’s still experiencing the problem. I’m unsure what to do next—seems like components work alone but not in combination. Could it be the 12VHPWR cable or a single connector on the power supply? Is my motherboard incompatible with 4090 models? Here are the specs: 7800X3D RTX 4090 FE, ASRock B650M-HDV/M.2, G.Skill Flare X5 32 GB (2×16 GB), DDR5-6000 CL32 Corsair RM1000x PCIe gen4 NVMe SSD, using direct-attach cables (excluding the included 12VHPWR adapter).
I would have started by testing with the original adapter cable first, as that's what was initially used for testing. Consider using a PCIe riser or connecting the graphics card directly to the motherboard's PCIe slot. Identify the old graphics card and use DDU to reset its drivers for a clean installation.
I'll include the original cables along with the adapter and send you an update. No rush—just using DDU now. The previous card was a 7900XTX (you don’t need to know why I changed, it’s a strange tale).
It looks like the cable might have been the issue. Appreciate the guidance!
