01 — Solution étape par étape
Solution étape par étape
STEP 01
Boot into Safe Mode
Force-restart the PC 3 times during boot to reach Recovery, then Troubleshoot > Advanced options > Startup Settings > Restart and press 4 (Safe Mode with Networking).
STEP 02
Uninstall the latest update
From Recovery, choose 'Uninstall latest quality update'. If the error started after a Windows update, this fixes it directly.
STEP 03
Run SFC and DISM
In Safe Mode open admin CMD and run 'sfc /scannow' then 'DISM /Online /Cleanup-Image /RestoreHealth'.
STEP 04
Scan the disk
Run 'chkdsk C: /f /r' and confirm the restart. The scan takes 20–60 minutes and repairs disk errors.
Don't power off during chkdsk. If the drive makes clicking sounds, back up immediately.
STEP 05
Check drivers
In Device Manager find devices with warnings; update GPU and chipset drivers from the vendor's site, or roll back a recently updated driver.
Conseils
