Anyway long story short, i changed the CPU in my computer (friend phoned overclockers.co.uk for me and checked that the new cpu is compatable with my motherboard and was told yes) and now on start up after the first loading page the computer gives me the option of either repairing windows or starting normally.
now if i start normally the pc just restarts itself and if i choose repair it goes to a blank screen and does nothing. (using windows 7 but dont have disk as it was an online upgrade from vista, also im on my dads pc posting this since my pc dosnt work ^^ )
now i understand if none of you can help me but my friend artellos tells me you guys are the best so im hoping you can ^^
