Windows 11 Pc randomly completely crashes

Symptoms:​

1. Complete Freeze and Black Screen: Your PC freezes, sometimes to the point where you have to restart it, and the monitor doesn't respond.
2. Restart Issues: After a restart, you lose Wi-Fi connectivity, which seems to happen regularly post-crash.

Possible Causes:​

1. Hardware Issues:
   • Power Supply (PSU): A failing PSU can lead to instability and random crashes, especially under load. If it’s unable to supply enough power to your components, this could lead to the behavior you're seeing.
   • CPU: If your CPU is overheating or failing, it might shut down to prevent damage. Checking the CPU temperatures during use with a monitoring tool like HWMonitor or Core Temp could help.
   • Faulty Components: RAM issues, especially with bad sectors, can cause random crashes. Running a memory test like MemTest86 might reveal problems.
   • Network Card: Though unlikely to cause the PC to crash completely, if the driver is corrupted or if there's a hardware issue, it could affect behavior when you reboot.
2. Software Issues:
   • Drivers: Ensure all drivers are up to date, particularly those related to graphics, chipset, and network components.
   • Windows Updates: Missing important updates could lead to stability issues. Make sure your Windows is updated.
   • Malware or Corrupted Files: Scanning for malware could reveal unwanted issues. Running a system file check (sfc /scannow) might identify and fix corrupted system files.

Recommendations:​

1. Power Supply Check: If possible, test your system with a different PSU.
2. Temperature Monitoring: Use a monitoring tool to keep an eye on your CPU and GPU temperatures during high usage.
3. MemTest86: Run this test to check your RAM.
4. Driver Updates: Visit the manufacturer’s website for your graphics card and network card. Download the latest drivers.
5. Event Viewer: After a crash, check the Windows Event Viewer for any error messages that can provide additional clues to the cause.

Next Steps:​

If you run through these checks and still face issues, we might want to discuss more specific replacements or repairs depending on what you've ruled out. Hopefully, this helps you diagnose and hopefully resolve the crashing issue! If you have any updates or further details to provide, feel free to share.
Good luck, and don’t worry about the grammar; your message is clear enough!

What to Do Next​

1. Restart Your PC: After any repairs, it’s a good idea to restart your computer to ensure all changes take effect properly.
2. Monitor Performance: Keep an eye on your system during regular usage to see if the freezing and crashing continue after the SFC repair. Look out for:
   • Any specific applications or tasks that provoke crashes.
   • If Wi-Fi connectivity issues persist after a crash and restart.
3. Run Additional Diagnostics:
   • Check the Event Viewer: If you experience crashes again, check the Event Viewer immediately afterward for any critical errors or warnings. It can sometimes provide insight into what causes the problem.
   • Use DISM Tool: If issues continue, consider running the Deployment Imaging Service and Management Tool (DISM) to repair the Windows image with the command:
     
     Code:

      DISM /Online /Cleanup-image /RestoreHealth

4. Further Investigate Hardware: If crashes resume, you might still want to check the previously mentioned hardware aspects, especially the PSU and RAM.
