It may be the psu because I replaced the mobo after it started to black screen.

No, I took it to best buy a while ago and they said it was the gpu and I replaced it and it still does the same thing

I have checked everything multiple times and it is all in the right places. Everything is hooked up how it should be.

Whenever I start up my pc the lights come on and the fans spin but I only get a black screen. I have no idea what to do please help.
