How do I troubleshoot a Windows 7 freeze or slowness?
I tried to run check disk and it retuned no errors or bad sectors. I also run CCleaner and also no effect.
What else can I do to determine the problem and solve it?
OS: Windows 7
I installed different application for data recovery and uninstalled them. Also I uninstalled any application that I installed recently
EDIT: I need to do hard reset to get out of freeze state
EDIT1: In safe mode it doesn't freeze
EDIT2:(Solved) I disabled all the services and the programs that loads on startup accept for security & microsoft services. My computer worked all night without freezing!
