Do you have a full installer of Win7 as opposed to just an upgrade?
If so I would backup, format, clean install Win7. If not, you might be able to upgrade to Vista and then upgrade to Win7, assuming you can find a Vista install (I had one somewhere).
It sounds to me like you have something messing with your video drivers. Have you got the latest drivers installed for your video card?
Are there any hardware conflicts being repoerted in Device Manager?
What are these 'other things' you're doing when watching movies? (No this isn't a reference to wanking over porn, that bit's assumed)
