Since you changed the MB you will have to reactivate. This is a Billy G thing to stop priating. John
I had to replace a motherboard and power supply on my friends compaq presario and since but you have to reinstall Windows XP( it says its already activated ) and brings you user login and when you click sign in, it asks to register XP again(probably windows way of making sure everyone can use the same disk).... so i tried putting a Windows XP backup disk so i can reinstall but it wont bring up the "boot off disk", anyone know of a way of making boot from disk so i can reinstall....
