Solution Steps
- 1 Press Windows key + X and select 'Device Manager'. Look for devices with a yellow exclamation mark. Right-click and select 'Update driver' → 'Search automatically for drivers'. If that doesn't work, go to the manufacturer's website and download the latest driver manually.
- 2 Press Windows key + R, type 'cmd', then press Ctrl+Shift+Enter to open Command Prompt as administrator. Run 'sfc /scannow' to repair corrupted system files.
- 3 Run 'DISM /Online /Cleanup-Image /RestoreHealth' to repair the system image.
- 4 Check for overclocking: If you overclocked your CPU or GPU, revert to default settings. Restart and press Del or F2 to enter BIOS/UEFI, load 'Optimized Defaults', and save.
- 5 Check the Event Viewer for more details: Press Windows key + R, type 'eventvwr.msc', and press Enter. Go to Windows Logs → System and look for critical errors around the time of the crash. Note the source and use that to identify the problematic driver.
- 6 If the error persists, perform a System Restore: Press Windows key + R, type 'rstrui.exe', and press Enter. Choose a restore point from before the problem started.
