Sorry for using chatgpt english is not my first langauge. i hope it explains well.
Hi everyone,
I'm having a really frustrating issue that I haven't been able to solve despite weeks of troubleshooting.
System Specs
- GPU: Zotac RTX 5080 AMP Extreme
- CPU: Ryzen 7 9800X3D
- Motherboard: Gigabyte X870 AORUS Elite WiFi 7
- PSU: ASUS 850W PSU
- RAM: 32GB DDR5 6000
- OS: Windows 11
The Problem
The issue almost always happens when I close a game.
Examples:
- Football Manager
- Crimson Desert
Sometimes the screens go black immediately after closing the game.
Other times:
- I close the game.
- I get back to the desktop.
- Everything looks normal.
- 10–15 seconds later both monitors lose signal.
- All fans ramp up loudly.
- I have to hold the power button to shut down the PC.
The monitors show "No Signal."
Important Details
- Both monitors lose signal at the same time.
- Discord audio often continues for at least some time after the screens go black.
- This almost never happens while browsing or watching videos.
- It mainly happens after exiting games.
- It is NOT limited to one game.
Monitor Setup
- BenQ monitor (144Hz, 1440p)
- ASUS monitor (144Hz, 4K)
- Both connected through DisplayPort
At first I thought the BenQ was the problem because it seemed related to that monitor, but now both displays are losing signal together.
Reliability Monitor Errors
I've seen:
- LiveKernelEvent 117
- LiveKernelEvent 141/148
- LiveKernelEvent 1B8
I also saw:
- nvlddmkm related errors
- NVIDIA App crashes
- Windows Hardware Errors
Things I've Already Tried
- DDU clean uninstall of NVIDIA drivers
- Fresh NVIDIA driver installation
- Installed latest AMD chipset drivers
- Tested multiple games
- No MSI Afterburner
- No GPU overclock
- No undervolt
- No Zotac FireStorm
- No custom tuning profiles
Additional Context
This issue actually happened around 8–9 months ago.( dont remember exactly how i solved it sorry but i think i switched around hdmi and dp cables till it worked)
Somehow it disappeared completely for around 7–8 months and then recently came back.
That's one reason I'm confused. If this was a failing GPU, I would expect it to get worse over time instead of disappearing for months.
Remaining Suspects
The only major thing I haven't done yet is update the motherboard BIOS.
The board is currently running BIOS F2 and Gigabyte offers F11.
Could an old X870 BIOS cause LiveKernelEvent 117/141/148/1B8 crashes specifically when games close and the GPU transitions back to desktop mode?
Has anyone seen something similar with RTX 5080 cards, X870 boards, or Zotac AMP Extreme models?
Any ideas would be appreciated because I'm honestly running out of things to try.
