PC won't start. No POST/BIOS/Beep/Display. Strange, slow clicking sound? (x-posted from r/buildapc)

So about a week ago my PC decided it no longer wanted to start up, with a mysterious clicking sound replacing any real attempt at starting. The sound is NOT a HDD failure, as even with none connected the clicking remains. There is no display on either monitor, no matter where they are connected, they don't even come out of sleep mode.

The clicking is approximately one every 4-5 seconds. I can't quite tell where it is coming from, maybe the PSU?

I've attempted:

• Removing the GPU

• Disconnecting all hard drives

• Removing the MOBO battery

• Replacing the Power Supply

• Switching the RAM to different slots

• Changing cords and SATA ports used

There are a ton of conflicting results from web searches(It could be a HDD, RAM, MOBO, PSU, CPU, random other things) but I fear I've eliminated all but CPU and the MOBO. I was in the market for a new CPU but if the Motherboard failed I'll have to go with that one first.
