Before installing SP2 go to the Dell site and update every device driver on the machine. Also make sure you do a BIOS upgrade. Then try to install SP2 - if you receive a message about a file from the manufacturer being newer than the one being installed then let it install over the manufacturer's driver - most likely the one from MS will work with SP2. If that doesn't work then before installing SP2 remove *all* hardware from the system board except 1 stick of RAM, 1 hard drive and the video card. If it works then start adding back hardware until you identify the problem device. If that doesn't work then go into the recovery console from the CD and run fixmbr and then try SP2 again.
