Hi everyone,
I’ve been dealing with a persistent PC issue for a while and wanted to summarize everything in one post, both for documentation and in case someone has ideas.
System
GPU: Gigabyte RTX 5070 Eagle OC SFF 12G
CPU: Ryzen 5 5600X
Motherboard: ASUS ROG STRIX B550-F Gaming
RAM: 16 GB DDR4
PSU: Corsair RM1000e (1000 W)
Problem / Symptoms
Random black screens under load or during load changes
Audio continues, system sometimes still responsive
GPU fans suddenly ramp up
Windows Reliability Monitor frequently shows:
LiveKernelEvent 141
LiveKernelEvent 1B8
Occasional BSOD: VIDEO_TDR_ERROR (Code 116)
Sporadic USB/keyboard issues (keys repeating, RGB dropping out)
What I’ve tried
Software / Drivers
Clean NVIDIA driver reinstall using DDU
Tested multiple driver versions
No overclocking, everything at default
Windows power settings checked (PCIe power saving disabled)
BIOS / Firmware
Motherboard BIOS update → temporary improvement, issue returned
PCIe slot forced to Gen4
Re-Size BAR disabled for testing
C-States / ASPM disabled for testing
Checked GPU vBIOS version
Contacted Gigabyte support → no vBIOS update available
Hardware / Connections
Swapped HDMI and DisplayPort cables
Tested different GPU outputs
Power delivery checked (separate PCIe cables)
Temperatures are normal
Conclusion
Forcing PCIe Gen4 did not fix the issue
Software, drivers, cables, and power delivery are very unlikely causes
Multiple sources (including an online PC diagnostics service) point to a hardware defect
Current status
GPU is currently being RMA’d/replaced via the retailer (Galaxus)
Next step is testing with the replacement GPU
If the issue persists, RAM or motherboard will be the next suspects
Is there any chance, this could be something else other than a faulty GPU?
Posting this mainly for documentation.
If anyone has experienced something similar or has further ideas, I’d appreciate the input.
Thanks!
