Ok so I am doing my first power on self test and it turns on. It goes into the bios, I see it sees my 8 gab if ram and all three drives. I also notice lights flashing. Btw I do not have my gpu connected yet, just using on board video. So I do nothing but just save and exit. Then it goes right back into the bios and never gets to the no operating system screen. I then tried to turn it off by the power button on the case but it did not work, had to flip the switch on the psu. My motherboard is a h170 asus pro gaming board. All the fans are spinning including the CPU fan and the system does recognize the CPU. What is going on?
