First I would uninstall PowerDVD. Then see if you have any continued problems. If not, then reinstall Power DVD and make sure you have the latest update on it. I agree with Bacillus - I don't see your BIOS as the problem.
Power DVD likes to have a startup thingy running - and that may be the problem. Open MSCONFIG, START UP tab, and uncheck anything related to PowerDVD. That may solve the problem. All that startup utility does is create an automatic association link so that any DVD movie inserted in the drive will automaticlly start Power DVD.
Being a control freak, I hate anything "automatic" w/o my command. I uncheck lots of those things - as a result, I never see freezes, crashes, or BSODs - not even with Power DVD.
