Description of Original Problem:
Since around August 2025, I’ve been having a crashing issue almost exclusively while playing Overwatch 2.
Originally, the crash looked like this:
- Monitor suddenly goes black for around 10 seconds
- Then says “No HDMI signal”
- Keyboard and mouse shut off
- PC itself stays powered on and case fans continue spinning
- Motherboard VGA/debug light turns on and stays on
- Only way to recover is turning the PSU switch off and rebooting
At first this happened very rarely, but over time it became more frequent.
I originally posted about this elsewhere and was told to update my drivers. After updating them, the issue completely stopped for around 3 weeks before returning. Someone also informed me the motherboard light indicated which component was failing, and when the crash happened again, I confirmed it was the VGA/GPU light.
Because of that, I assumed my graphics card itself was defective and bought a brand new GPU of the exact same model. The issue still happened within about 15 minutes of installing the replacement card.
Around March 2026, a second crash started happening. If I alt-tab out of Overwatch 2, my PC becomes laggy/stuttery and then the game closes with a “Rendering Device Lost” error.
Now both crashes happen:
- black screen/no HDMI signal crash
- “Rendering Device Lost” crash
The issue is almost entirely isolated to Overwatch 2. My PC otherwise behaves normally during regular use and other games.
Troubleshooting:
- Updated GPU drivers
- Uninstalled and re-installed the drivers (I believe my friend called it a "clean reinstall")
- Reported crashed through AMD
- Replaced PSU
- Replaced GPU entirely with another RX 7600
- Ran Windows Memory Diagnostic (no issues found)
- Monitored temps (appear normal)
- Checked cables/connections
- Checked Event Viewer (only improper shutdown logs)
