Solution Steps
- 1 Boot into Safe Mode: Restart your PC and press F8 (or Shift + Restart) to access Advanced Startup Options. Choose Safe Mode with Networking. This loads minimal drivers, helping you determine if a driver is causing the issue.
- 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 likely have a faulty RAM stick that needs replacement.
- 3 Check disk for errors: Open Command Prompt as administrator (right-click Start → 'Terminal (Admin)'). Run 'chkdsk /f /r' on your system drive (usually C:). This scans for and repairs disk errors that could corrupt the PFN list. You'll need to restart to let the scan run.
- 4 Update or roll back drivers: Open Device Manager (Windows key + X → Device Manager). Look for devices with a yellow exclamation mark. Right-click and select 'Update driver'. If the error started after a recent driver update, use 'Roll Back Driver'.
- 5 Disable overclocking: If you've overclocked your RAM or CPU, revert to default settings in BIOS/UEFI. Overclocking can cause memory instability, leading to this error. Enter BIOS by pressing Del or F2 during boot and load default settings.
