My PC after building it initially boots perfectly then once I shut it down and leave it over night the next morning it takes anything from 5min - 20 mins I've tried another drive still the same problem I've tried swapping ram and slots no difference only thing that helps is resetting the bios (I don't change anything in) and next boot it works ,takes less than 40 seconds to load up.
