Lockups

[AChimp]

Go to the Start > Run menu and type "msconfig". On the Startup tab, you can start turning off the programs that Windows will run when it loads. Playing with these might help you narrow down which one is causing the problem.

If this doesn't fix the problem, it's probably a corrupted system file, but Safe Mode loads properly so it's probably something that Normal Mode is loading that's messign up.
