For some reason one of our machines - a Dell Dimension 2400 running XP home
- is having big problems. Processes stop responding after a short while
after booting up - eg Firefox - and hang for about 10-20 minutes. Then the
processes unfreeze and the machine seems to be fine. Task Manager works -
it shows each non-responding process is duplicated - but these processes
cannot be terminated.

Any ideas? Running Zone Alarm on this PC. Also, I reinstalled XP a few months ago.

Thanks
