My order came today, i went by the book setting everything up and it was fine, i started windows and my desktop came up.. after 5 seconds my computer switched right off and started up straight away, after giving me options of safe mode and starting windows normally ect it proceeds to load.. then when the windows logo pops up saying 'loading' 5 seconds pass and it restarts from no ware jumping back to the mother board screen, this process keeps repeating its self and i have no idea what to do! any help would be appreciated!
