So I recently got an EVGA z170 Stinger, an i5 6400, and 2x4 gigs of Geil Super Luce DDR4 ram to upgrade my old system. I deleted al nvidia drivers (possibly to prevent any compatability errors, dont think it really had any affect) on my hard drive for the gpu (which I am not changing) but could not locate any AMD ones for the CPU (it was an amd A8 5500). After hooking everything up, hard drive included, I powered on the system through a power button on the mobo. Unfortunately, the system, while it looked to be working fine hardware wise, was not sending anything to the monitor. So, having no other option, I held the power button to turn off the system and try and troubleshoot. I unplugged the HDD connections and took out the gpu but when I turned on the pc it would seem to pulse power, not fully turning on and still not sending info to my monitor. I tested the ram and it is not the problem. Unplugging the cpu power connectors on the mobo but leaving the big mobo one in caused steady power to the mobo and ram, not the pulsing effect. What could be causing this and how can I fix it, if I can?
