Question Just upgraded CPU to Ryzen 5 2600. Now my monitor isn't detecting input

Today I got a new Ryzen 5 2600 and I replaced my old a8-9600. The motherboard is the Asus prime a320m-k. It supports the chip and the bios is up to date. Upon replacing the processor and cooler, my pc no longer outputs to the monitor. It turns on, fans spun and everything, but no boot.

I have:
Reseated the GPU, RAM, and CPU several times
Removed and reseated the CMOS battery

Also I will say that it still boots up fine when trying to use my old processor.

I will say that my keyboard lights up for a second before turning off ( oh yeah my keyboard and mouse also don't turn on or work with it)

Any help is appreciated!
