Gigabtye ga-ab350m-ds3h motherboard , ryzen 1700x, 16gb of Pacific sun ram(2400hz), gtx 1070. I downloaded ryzen master to see my cores and I seen that i only had 4 out of eight cores so I look online and found out I needed to up date my bios so I did computer booted and worked fine but in ryzen was telling me about that i still only had 4 cores available so I updated my bios to a older version, after my bios said that it had been successfully updated it said that it wanted to reboot so it TRIED to and stayed stuck on a blank screen for 10 min. So I powered the PC down. Now Everytime I turn on my PC it turns on and the fans start spinning at a regular rpm them goes up a little then just go back down over and over with no boot. I tried clearing cmos but that did not work ethier. PLEASE HELP
