After completing a build and powering it on for the first time, the lights on the motherboard flicker on and off, then stay on after around six times, then the computer fully turns itself off and on again. There were no beeps comping from the motherboard. Any idea what could have caused this?
system is as follows -7700k, gtx 1070, 16 gigs of ddr4 2133mhz, gigabyte ga z270 motherboard, EVGA supernova650 80+ gold, tp-link wireless dual band pci express adapter, and an m.2 and HDD.
Any help would be greatly appreciated!
