So I have a problem. My PC will not boot to BIOS. I've been able to jump my PSU and my motherboard peripherals and light blink when I turn power on. As far as I know my RAM is good and seated well. I've seated my CPU in well, no bent pins. I will say I noticed some thermal paste on the side of the CPU. Right now ive got just the minimal things hooked up. I suspect the heatsink, maybe RAM. I'd like to get some opinions/fixes.

CPU: Ryzen 7 2700x
MOBO: Aorus A520
PSU: Corsair RM850x
RAM: HyperX Fury

Edit: I forgot to mention that the power switch is not working so I tried jumping the system with a screwdriver and no dice.
