After I fixed a boot problem ( http://superuser.com/questions/113187/how-to-fix-winload-exe-is-missing-or-corrupt-issue-on-windows-7-startup ), I ran into this hang problem again.
My system hanged at login screen, i.e. where I was supposed to input the password. I could not even move my mouse.
Then I tried these steps below:
- Started system with 'Safe Mode with Network Connection'. It worked fine. No hangs.
- Disabled 'Startup Items' in 'msconfig' and restart. System hanged again.
- Use 'Diagnostic startup' in 'msconfig' and restart. System hanged again.
- Then I tried to uninstall 'Norton Internet Security 2010' in Safe Mode as Step 1. System hanged quickly after startup of uninstallation process.
I am not quite sure if NIS 2010 is related to this problem. But how can I uninstall it manually? or how can I just disable its system driver?
