I built a new gaming PC about a month and a half ago and its been running fine up until now. I turned it on a couple of days ago and Win 7 was freezing up. The mouse cursor was a blue wheel and I couldn't click or do anything. I couldn't even access the command line and ctrl+alt+del didn't work either. At this point it did boot up in safe mode. I powered it down and now it won't boot past BIOS. I reseated everything and checked all the connections and everything seems good.
