Please try right-clicking on the file that starts up the game, then select "properties". On this screen, go to the "compatibility" tab. In this tab, place a check mark in the box that says "run this program in compatibility mode for" and then select "Windows XP sp2."
Then click "ok", and give it a try.
If this doesn't work, please check that you're running the game as administrator by right-clicking as above, then select "Run as Administrator".
If neither of those work, then I would suspect the video card drivers. Perhaps they need updating.
Good luck, sounds like you have a nice new gaming rig. I'm extremely jealous!
