My computer hangs at start up & when I logg off it then it works, please help me to solve this problem. ????

Answer 1

Have you tried Safe Mode? If yes, does it work properly? If it works properly, then you probably have too many things running, or you have some malware.

Use Starter ( http://www.snapfiles.com/get/starter.html ) or What's Running ( http://www.whatsrunning.net/WhatsRunning/Download/WhatsRunning2_2_Setup.exe ) to help you manage your startup programs.

For malware problems, you want to scan with some anti-spyware programs and antivirus programs.

Spybot Search & Destroy ( http://www.safer-networking.org/en/download/index.html )
