Ok well after I finaly got my brand new mobo after damaging the last I desided to put the FSB at only 140.. but my damn mobo didnt seem to like that and corupted part of windows so I had to format and re-install... but when I went to reinstall windows I had to enter that product registration code.. but then I rembered that I had stuck that stupid little sticker on the back of my old case.. I then looked at the back of my old case to only see it gone!! It either fallen off or I had taken it off without realiseing it when I was cleaning out the old case!!! Now what am I supose to do! Microsoft any just gonna go and give me a new cd key now are they?! Ah man... this is like the fifth prob Ive had so far in switching to my new setup... arggg.....
