Solution Steps

1 Press Windows key + R, type 'eventvwr.msc' and press Enter. In Event Viewer, go to 'Windows Logs' → 'System'. Look for critical errors around the time of the crash. Note the source and event ID. This helps pinpoint the faulty driver.
2 Press Windows key + X and select 'Device Manager'. Review all devices, especially display adapters, network adapters, and storage controllers. Right-click any device with a yellow exclamation mark and choose 'Update driver'. If no updates are found, go to the manufacturer's website and download the latest driver manually. Faulty drivers are a common cause.
3 Open Command Prompt as administrator (Win+R, type 'cmd', press Ctrl+Shift+Enter). Run 'sfc /scannow' and press Enter. This scans and repairs corrupted system files. After it completes, restart your PC.
4 If the error persists, run 'DISM /Online /Cleanup-Image /RestoreHealth' in the same Command Prompt. This repairs the system image. After completion, restart and run 'sfc /scannow' again.
5 If the problem continues, boot into Safe Mode. Press Windows key + R, type 'msconfig', go to 'Boot' tab, check 'Safe boot' and select 'Minimal'. Restart. If the system is stable in Safe Mode, uninstall recently installed software or drivers, then revert to normal boot.
6 If nothing works, use System Restore: press Windows key + R, type 'rstrui' and follow the wizard to restore to a point before the error.
