Interactive Fix Checklist
0 of 5 steps completedSafety power-off and discharge
Shut down the PC, turn off the power supply rocker switch (O), and unplug the AC power cord from the wall outlet. Press the front power button once while unplugged to discharge residual capacitor energy before touching any internal components.
Run MemTest86 on each RAM stick individually
Create a bootable MemTest86 USB drive and test one stick at a time. A single error in Test 6 or 8 confirms hardware memory replacement is needed.
Run CHKDSK to repair filesystem metadata
Open Command Prompt as Administrator and run 'chkdsk C: /f /r'. Reboot to let Windows scan nonpaged storage blocks.
Recreate the Windows Pagefile
Go to System Properties → Advanced → Performance Settings → Advanced → Change Virtual Memory. Set to 'No paging file', reboot, and reset to 'System managed size' to discard corrupted pagefile blocks.
Disable third-party antivirus suites
Third-party kernel-level antivirus drivers frequently trigger nonpaged memory faults. Temporarily uninstall to isolate.
