We just had a power outage and I didn’t have my PC on a UPS (it's in the mail now). So it went under and has not come back up yet. It will turn on and off with the power button but shows nothing but a black screen. It will not boot into bios. All of the fans spin and the hard drive that’s in there (I have an SSD and a HDD) makes noise so I can tell most everything is getting power. Everything else connected to the motherboard seemed to be working - All fans, gpu, HDD. So I swapped out my CPU with the old one (just upgraded from i5 to i7) and still no luck. The last thing I tried was swapping the ram around in their slots and replacing the ram sticks with different ram but that didn’t do anything either. I also completely removed the gpu to see if that was causing an issue. I'm now under the influence that it's either the mobo or the psu. Any ideas what it could be? Should I take it to someone?

If you know the monitor is ok, possibly the next step would be to REMOVE the GPU from the PC and connect the monitor cable to the motherboards onboard graphics and reboot.
If that still doesnt work can you get another known good power supply unit to test the system with?

Unless you can borrow or steal a PSU, and possibly other hardware then yes it may be better to have it professionally diagnosed. About the only way to diagnose is to substitute known good parts for the existing ones. Hopefully not in your case but often when PSU's fail they take out other parts including the motherboard as well.
Good luck with it.
