Check Hard Drive for Errors
Bad sectors or file system corruption can silently corrupt DLL files, leading to intermittent 0xc000007b errors.
One-Click Script
Save as schedule-chkdsk.bat, right-click → Run as Administrator.
@echo off echo This will schedule CHKDSK on next restart. echo It will check for bad sectors and fix file system errors. echo This may take 1-4 hours depending on drive size. echo. chkdsk C: /f /r echo. echo If prompted, type Y and restart your computer. pause
Step-by-Step
- 1
Open Command Prompt as Administrator.
- 2
Check the C: drive: chkdsk C: /f /r
- 3
/f fixes errors. /r locates bad sectors and recovers readable information.
- 4
You will see: "Chkdsk cannot run because the volume is in use... Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)"
- 5
Type Y and press Enter.
- 6
Restart your computer. CHKDSK will run before Windows loads. On large drives this can take 1-4 hours.
- 7
After boot, check the results in Event Viewer: Windows Logs → Application → filter by "Wininit" source.
How to Verify It Worked
- Event Viewer Wininit log shows "Windows has checked the file system and found no problems."
- No more random application crashes that previously worked.
Still Not Working?
If CHKDSK finds unrecoverable bad sectors, your hard drive is failing. Back up data immediately and replace the drive.
