The device malfunctioned due to an unknown reason.

Question

Peace be upon you, brothers. For about four months now, my computer has been crashing on its own with any game, even light ones. The school computer runs them better than mine. This problem has been happening for a while now, and I need a solution. I've checked all the parts and they're fine, but the computer still crashes.

This behavior can occur for several reasons. It is necessary to investigate.

Please do the following:

Export and share the log for analysis:

1. Press Windows + X and select Event Viewer;
2. Expand Windows Logs and select System;
3. In the Actions panel on the right, select Filter Current Log;
4. In Event level, check the boxes Critical, Warning, and Error and click on Ok;
5. Again, in the Actions panel, select Save Filtered Log File As and save in an easily accessible place.

Then, upload the file to the cloud (OneDrive), choose to share it, and get the link.

Post the link to the file here so I can have a look.

I await your reply.

The crashes shown in the screenshots are application crashes (unhandled exceptions in game executables and system DLLs like ntdll.dll), which are commonly caused by faulty drivers, corrupted system files, or unstable hardware/drivers rather than the games themselves.

Follow these steps on Windows 11 to isolate the cause:

1. Check for stop code errors or BSODs

• If the system sometimes shows a blue/black screen with a stop code before restarting, note the exact stop code text (for example, MEMORY_MANAGEMENT, PAGE_FAULT_IN_NONPAGED_AREA).
• Use the guidance in the bug check documentation to match the scenario and apply the related troubleshooting steps (driver issues, faulty devices, memory errors, file system errors, etc.).

2. Update or roll back device drivers

• In Device Manager, look for any device with a yellow exclamation mark.
• For display (GPU) and other critical devices, update to the latest stable drivers from the manufacturer.
• If crashes started after a recent driver update, roll back that driver.
• For each device with issues, open its properties → check the events log and update or reinstall the driver as needed.

3. Check for hardware or driver faults Use the general bug-check troubleshooting guidance:

• Remove or disconnect any recently added hardware.
• Run the hardware diagnostics provided by the PC or motherboard manufacturer.
• Confirm all internal cables and expansion cards are properly seated.

4. Test system memory

• Run the Windows Memory Diagnostics tool:
  • Open Control Panel → search for “Memory” → select “Diagnose your computer’s memory problems”.
  • Let the test run and then check the results in Event Viewer under the MemoryDiagnostics-Results entry.
• If memory errors are reported, replace or reseat the RAM.

5. Check disk and system files

• Run a file system check on the system drive:
  • In File Explorer, right‑click the system drive → Properties → Tools → Check.
• Run System File Checker to repair corrupted system files:
  • Open an elevated Command Prompt and run: sfc /scannow.
  • If SFC reports corruption that it repaired, test the games again.

6. Ensure sufficient free disk space and updates

• Keep at least 10–15% of the system drive free so Windows and games can create temporary and paging files.
• Make sure Windows is fully updated with the latest quality updates and, if applicable, the latest service pack/feature update supported by the device.

7. Scan for malware or system corruption

• Run a full antivirus scan.
• If malware or heavy system corruption is suspected and crashes persist after the above steps, consider using Windows’ Reset this PC feature with “Keep my files” to reinstall Windows while preserving personal data.

If, after these steps, the system still crashes only during games and no memory/disk errors are found, focus on GPU drivers and any overclocking or tuning utilities: disable or uninstall them and test again.
