Dell is replacing my week old Inspiron 600m with a new system because there's something wrong with my video card.  When I get the new computer, can I just swap the drive from the first system into the new system so that I don't have to reconfigure and reinstall software, etc.  If so, will the new computer still recognize its service tag and express code and stuff like that? Will I have to update the bios?  Any info is greatly appreciated.  Thx.
