System optimization causing system instability

4.5

After "optimizing", your computer is now crashing, showing blue screens, or missing features.

Symptoms
  • BSOD on boot
  • Start menu not working
  • "DLL not found" errors
Possible Causes
  • Registry over-cleaning
  • Deleted system drivers
  • Disabled essential services

Step-by-Step Fix

1

Use System Restore

Roll back to the point before you ran the optimization tool.

2

Run SFC Scan

Run "sfc /scannow" in CMD to repair any deleted system files.

3

Undo Changes in App

Most good optimization tools have an "Undo" or "Restore" feature.

When to See a Technician

Registry cleaners are particularly dangerous and rarely provide any real performance benefit.
