I installed a OEM copy of Windows XP Home Edition. I brought a new PSU which damaged my hard drive when it blew!. So i had to format my hardrive and reinstall windows.
The problem is i can't activate my copy of Windows as when i use the oroginal product key it says it has already be activated on a different pc.
Is there anyway i can still register this copy of Windows with my pc as i get the stupid 30 days notice etc and after that my pc won't let me onto the OS.
