ok so hears my problem. my computer is a dell xps 410. I've had windows xp for awhile and i've always had the disc for windows vista but never downloaded it. I've finally downloaded it and now i'm having many problems.
its taking forever to load. whenever i open mozilla firefox or internet explorer it will take forever to open a page. When i try to go to videos they never load. most of the time it just times out and won't open the page at all. why is this happening and what do i have to do to fix this?

If you are not having problems with the XP, just go back to windows XP.
