Postup řešení

  1. 1 Run System File Checker: press Windows key + X → Terminal (Admin) → type 'sfc /scannow' → Enter. This scans and repairs all protected Windows 11 Pro system files.
  2. 2 Run DISM: in the same admin terminal, type 'DISM /Online /Cleanup-Image /RestoreHealth' → Enter. This repairs the component store that SFC uses to fix files.
  3. 3 Check for Windows 11 Pro updates: Settings → Windows Update → Check for updates. Install ALL pending updates.
  4. 4 Scan for malware: Windows Security → Virus & threat protection → Scan options → Full scan → Scan now.
  5. 5 Check disk for errors: open admin terminal, type 'chkdsk C: /f /r' → Enter → Y → restart. Disk errors corrupt system files.
  6. 6 Run Windows Memory Diagnostic: Win+R → 'mdsched.exe' → Restart now. Faulty RAM causes random system crashes.
  7. 7 Perform a Clean Boot: Win+R → 'msconfig' → Services → Hide Microsoft services → Disable all → Startup → Open Task Manager → Disable all → Restart. This identifies conflicting third-party software.
  8. 8 Update all drivers: GPU (NVIDIA/AMD/Intel website), chipset, network, audio, storage. Manufacturer websites, not Windows Update.
