Have you tried upgrading to Windows 7? It works much better than Vista. My laptop loves it. Make sure you do a compatibility test first though, or a search for Windows 7 compatible drivers (especially audio and video) for your computer.
Good News, I got it to working but it only runs in safe mode. EDIT: I just restarted and it seems that everything is working now. All I did was a system restore in safe mode! 2nd Edit: Ok, I think I got too happy too fast. Google Chrome is the only thing that will run. iTunes, Windows Media Player, and Internet Explorer won't open. Anyone have any ideas?
Don't just burn out cash for no reason, it's a computer that costs money. I'd recommend you take a look see and do some investigation on google. Tired of people posting random crap. If you want to help, don't post stupid things you won't do yourself, unless you have the money to do so. Just to start you off... http://social.answers.microsoft.com/Forums/en-US/vistaprograms/thread/039ceca1-c81f-4136-8c04-bf13c0378495
