I manually turned of my PC a bit ago and whenever I would turn it on it would turn on then off repeatedly until I turned it off. I switched the RAM and now it stays on but there is no display in my monitor and my keyboard and mouse aren't on, even when plugged in. I have tried different ports to. Here are my PC specs. GPU: GeForce GTX 1080, CPU: i7-7700k, Motherboard: ASRock Z270M-ITX/ac, HDD (D) TOSHIBA DTO1ACA200, SSD (E) KingFast, SSD (C) KINGSTON SUB400S37240G. 16GB of RAM. PSU - CIN: 0750AL163536. P/N: 210-GQ-0750.

I would try to clear your BIOS and see if this helps to start.
