:It sounds like you might be having some sort of memory problems. I'm not sure what Dell uses but it's probably crap.
Windows Media player has some known problems in Vista. Mainly that it has been known to not quit when you close the program. Also, you should know that dreamscene is sort of a resource hog and may slow down your system unless you have very good video capabilities.
However, it sounds like you are having a far more general problem than any of the ones I have mentioned. Has Dell swapped the mobo? Can you get them to send you a DVD with the OS only (without all of their "bonus" stuff) on it?

I have the Windows DVD. It came with my system. I have formatted and installed with that DVD. It doesn't include anything extra and doesn't have any drivers. I have another Dell CD with Drivers
