Ok here is the deal: I had Vista ultimate 32 bit installed on an Asrock 939 dual sata board using AMD 3800+ x2 939 socket cpu. I got a new motherboard and cpu...Asrock A780GXE/128 AM2 board and AMD 5050e dual processor cpu. Plugged everything in using same psu, same harddrive, and same 2 dvd drives. Booted up to see if I get a post which worked fine. Decided to see if it booted into Vista and to my surprise it did without a hitch. Vista found all my hardware installed drivers and drivers for the board. All I needed to do was install Ethernet drivers. It is working great...no exclamation marks in device manager. All my programs start up fine. Vista says 3 days to automatic activation (Guess this relates to new board and cpu). My question is should I format C and reinstall Vista? I know this is a judgment call but would like suggestions....Given I have same motherboard and cpu brands is this why I had no boot issues....Thanks.
