The specific stop code mentioned is:
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
This error means a driver or system process caused an unhandled exception — often due to faulty or incompatible drivers, hardware issues, or corrupted system files.
Common Causes
-
Faulty or outdated drivers (especially display, network, or storage drivers)
-
Corrupted Windows files
-
Recent hardware change (RAM, GPU, USB devices)
-
Overheating or unstable overclocking
-
Antivirus or third-party software conflicts
Step-by-Step Fix
1. Boot into Safe Mode
Turn off your computer.
Turn it back on and immediately press F8 (or Shift + F8 on older systems).
If that doesn’t work:
Turn off and on 3 times during the Windows loading screen — it’ll trigger Automatic Repair.
Choose Advanced options → Troubleshoot → Advanced options → Startup Settings → Restart.
Select 4) Enable Safe Mode.
2. Identify the Faulty Driver
While in Safe Mode:
Press Windows + X → Device Manager.
Look for devices with a yellow triangle.
Right-click → Update driver, or if recently installed → Uninstall device.
Reboot normally.
You can also check the C:\Windows\Minidump folder for .dmp files — these show which driver caused the crash. (You can upload one and I can help read it.)
3. Run System Repair Commands
Open Command Prompt (Admin) and run:
sfc /scannow
Then:
DISM /Online /Cleanup-Image /RestoreHealth
Both commands repair corrupted system files.
4. Update or Roll Back Drivers
Update GPU, network, and chipset drivers from the manufacturer’s site.
If you recently updated one, roll it back:
Device Manager → right-click driver → Properties → Driver tab → Roll Back Driver.
5. Check for Overheating or RAM Errors
Run Windows Memory Diagnostic (mdsched.exe).
Ensure your system isn’t overheating — clean vents and fans.
6. If Still Not Fixed
You can:
Use System Restore (to a point before the issue started).
Or Reset This PC while keeping files (Settings → System → Recovery).
