(Boson 3.0)First time built PC no monitor signal, no power on keyboard or mouse.

[Sheng_]

I've tried almost everything online but it still refuses to connect to my monitor, mouse and keyboard. I built the Boson 3.0 by Austin Evans (check it out on youtube, it's called "How to build a gaming pc 2016") but despite changing the ram stick's slot, reconnecting cables, with and without graphic card, made sure I ground myself, connect VGA and HDMI to different monitors on the motherboard and graphic card but still no luck. Everything else is fine though, the fans run, powers are on, no beeps unless graphic card is not installed (it beeps 4 short, 1 long, then 2 short.) Tbh idk what to do anymore, I'm just lying on the floor muttering nonsensical lyrics while looking at my beautiful yet useless brick of a computer.

4 short beep ：Real Time Clock malfunction

1 long beep and 2 short beep：Graphic card error (of course if theres no graphics card you will get this one)

Did you exactly the same parts he did??????
I see people say use the onboard video port and upgrade the bios to newest verson but you said you cant get onboard video output.
also check the battery with a volt meter and make sure it reads 3 volts.

you need to plug it into the graphics card not the motherboard slot
i had the same problem
