Download OTL by OldTimer to your Desktop.

• Close all windows and double click OTL.exe
  
• Click Run Scan and let the program run uninterrupted
  
• It will produce two logs for you, one will pop up - OTL.txt, the other will be saved on your Desktop - Extras.txt. Post both logs in this thread.
  
• You may need to use two posts to get it all.
  

how do i do that when ass soon as i put my password in to access my computer it goes to that screen

Hello.

Please then reboot your computer in Safe Mode by doing the following :

• Restart your computer
  
• After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  
• Instead of Windows loading as normal, the Advanced Options Menu should appear;
  
• Select the first option, to run Windows in Safe Mode, then press Enter.
  
• Choose your usual account.
  

Can you run OTL in Safe Mode?
