Whenever I attempt to convert a movie my pc either hangs after 2-3 minutes or the converting software just shuts down (again after about 2-3 minutes). I've tried canopus, tmpgenc and others but still the same. The software's ok as other people I know are using it with no problems. I've tried all the suggestions i've found on the forums but no joy I've increased to 768MB of ram from 256 on the advice of a friend but no change. My processor is a Celeron 1.7GHz (beneath this on the system properties it says 1.96 GHz). I have checked that the bios is set to default so I can't see how it's overclocked. Oh yeah, my CPU maxs at 100% when I try to convert a movie. I'd really appreciate some guidance, i've been sitting here tonight for over 5 hours trying to sort this and i'm at my wits end!I can't believe this isn't happening to anyone else! thanx in advance.
