I built a computer using an ASROCK X370 Fatality Gaming X and AMD A6 3.5GHz CPU and before the power supply went out it would boot, and now that I got a new power supply it won't boot. It keeps giving me the debug code 7A (Chipset Initialization) error code for a minute or two before shutting the PC off. I tried resetting the CMOS but it does not work. It had a series of other codes, but I've not gotten them since I straightened out the problems that caused those codes. What do I need to do to get rid of the 7A Debug code and get my computer to boot??
