Okay so i finally got my motherboard, mounted it, with all parts..
Starts installing vista, im like woohoo.. then.. when its about to finish.. a window pops up

"Windows cant configure the hardware of this computer"
*translatet from swedish, might not be in right order...*

so i was like.. W T F...
Im now trying to install xp .. dont want it because i loose some RAM memory and i cant use Directx 10.
What could it be?

Also when i start the computer i get this message
