How to fix error windows-randomly-restarts-no-bsod in Windows 11

Solution Steps

1. 1 Press Windows key + X and select 'Event Viewer'. This tool logs system events, including unexpected shutdowns. We'll look for critical errors that indicate the cause.
2. 2 In Event Viewer, go to Windows Logs → System. Look for Critical events with source 'Kernel-Power' (Event ID 41). This indicates the system restarted without a clean shutdown. Note the timestamp and any other error codes.
3. 3 Check for overheating: Download a temperature monitoring tool like Core Temp or HWMonitor. Run it while performing a stress test (like Prime95) to see if CPU temperatures exceed 90°C. If they do, clean the dust from fans and heatsinks, and ensure proper airflow.
4. 4 Test your RAM: Press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This runs Windows Memory Diagnostic, which will test your RAM for errors. It may take 30 minutes.
5. 5 Check your power supply: If you have a multimeter, you can test the PSU voltages, but it's easier to swap in a known-good PSU if you have one. If not, listen for unusual noises from the PSU and check if it's hot to the touch.
6. 6 Disable automatic restart: Press Windows key + R, type 'sysdm.cpl', and press Enter. Go to Advanced tab, under Startup and Recovery, click Settings. Uncheck 'Automatically restart'. This will show a blue screen instead of restarting, which can give you an error code to research.
7. 7 Update your BIOS and chipset drivers: Visit your motherboard manufacturer's website and download the latest BIOS and chipset drivers. Outdated BIOS can cause instability.
8. 8 If you have overclocked your CPU or RAM, reset them to default settings in the BIOS. Overclocking can cause random restarts if unstable.
