How to fix error 0x000000c1 in Windows 11

Solution Steps

1. 1 Boot into Safe Mode: Press Windows key + I, go to System → Recovery → Advanced startup, and click 'Restart now'. Then choose Troubleshoot → Advanced options → Startup Settings → Restart, and press 4 for Safe Mode. Safe Mode loads minimal drivers, so if the error doesn't occur in Safe Mode, it's likely a driver issue.
2. 2 Run Windows Memory Diagnostic: press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This will test your RAM for errors. If errors are found, you may need to replace the faulty RAM module.
3. 3 If memory tests pass, the issue is likely a driver. In Safe Mode, press Windows key + X and select 'Device Manager'. Look for devices with a yellow exclamation mark. Right-click and select 'Update driver' or 'Uninstall device' if needed. Restart after making changes.
4. 4 Run the System File Checker: press Windows key + R, type 'cmd', right-click and select 'Run as administrator'. Type 'sfc /scannow' and press Enter. This repairs corrupted system files.
5. 5 Check the system event log for clues: press Windows key + X, select 'Event Viewer', and look under 'Windows Logs → System' for errors around the time of the crash. This can help identify the problematic driver.
6. 6 If the error persists, consider updating your BIOS and chipset drivers from your motherboard manufacturer's website. Outdated firmware can cause memory corruption.
