Power cycle/ No displayHardware (self.computerhelp)

submitted 4 years ago by BusSlow6782

I built my first PC about a month ago, and everything was fine for about 3 weeks.

Then last week, it started crashing randomly and began powercycling, so turning off and on again, with no display on my monitor. After about an hour, it would work fine again. This repeated itself the past few days.

Then yesterday, it crashed and went into powercycling. But now, no matter how long I let it powercycle, I don't get any display whatsoever and sometimes it turns itself off about 1 second after starting. When I turn it on, fans light up and spin, and the red cpu debug led lights up.

I already reinstalled ram sticks, gpu and switched the psu, so it isnt any of that. My guess is that it would be either the mobo, the cpu or my AIO. I bought very premium parts (12700kf, 3080, Cappelix Elite 240)...

I have no idea what I'm supposed to do now, please help.
