RTX 5080 ROG ASTRAL random black screens / no signal issue, possible faulty GPU?
Hey everyone,
I recently installed a brand new ASUS ROG Astral RTX 5080 OC into my PC. The card was bought sealed and looked completely new. At first everything worked perfectly, but after some time I started getting random black screens / no signal on both monitors at the same time.
Important details:
- Both monitors lose signal simultaneously (DP + HDMI)
- GPU RGB and fans stay on
- Sometimes happens during normal desktop use or idle
- Sometimes happens on boot
- Event Viewer shows nvlddmkm / TDR related errors
- No overheating or artifacting
- GPU benchmarks and games normally most of the time
- Happens fully randomly, I couldn't detect a pattern
Things I already tried:
- DDU + clean NVIDIA driver reinstall
- Older and newer NVIDIA drivers
- Reset GPU to stock settings
- BIOS defaults
- Disabled hardware acceleration/HAGS
- Reinstalled NVIDIA App
- New native Corsair 12V-2x6 cable
- Different HDMI/DP cables
System:
- RTX 5080 Astral OC
- i7-14700F
- Gigabyte B760 GAMING X DDR4
- Corsair RM850x Shift 850W
- 32GB Corsair Vengeance DDR4 (yes i know, should be ddr5)
Before installing this GPU, my previous GPU worked perfectly fine in the exact same system.
ASUS support basically told me I already did all the normal troubleshooting and suggested warranty/retailer handling, but the GPU originally came from a sealed auction item so I currently don’t have the original retailer receipt.
Has anyone experienced something similar with 50 series cards or random nvlddmkm/TDR signal loss issues?
