You should not use Dell Cd under Win7. Really. Instead use Dell Diver download page for Win7 (except for the videocard drivers, you must get it from Intel GMA500 download page). It is for XP and most of the drivers doesn't work at all causing problems.
However the only driver you must really get is the video driver from Intel the card reader driver from Dell... Except for Tv Tuner all the things will work out of the box in Win7.
For Tv tuner try the drivers on the cd, but I don't have it so I don't know.
Other utilities and driver will probably only slow down your Mini, remember, our Mini's have only 1 gb ram... Even the smaller driver or application will eat it.
If you want advanced Bluetooth features install the win7 bluetooth driver from Dell.
The GMA500 Guru: ask me for every video problem! (Or if you desire a perfect video experience)
