Usually when a pc "locks up" it is actually doing something you can not see? I use a old app named process explorer (procexp.exe) that will let you see inside the various tasks and actually look at what each dll is doing. It is much better detailed than the standard task manager as it will let you see and stop a certain dll or script. You can then look at what the offender is on the web to see what has happened.
