Hey buy_food for future reference the yellow exclamation marks in the device manager mean problems and almost always problems with drivers. If you follow Noo's link you can download all of the drivers from Dell's site and install them. Also make sure that under the display adapter in device manager it lists your video card not a standard display adapter. As to the games freezing up make sure you have a current version of Direct X running that you can find at Microsofts website under downloads.
