Help! No post after reapplying thermal paste!

[ganestalay]

So my setup was Ryzen 5 2600x

gskill 2x8gb ram

cryorig h7 cpu fan

sapphire nitro+ rx 580

750w gold evga psu

msi b450 motherboard
My PC was fine, I built it and used for 4 days, until I noticed CPU was in abnormal temperatures.

So I disassembled PC, unplugged everything, and reapplied my thermal paste. I reassembled my PC, and everything was fine until I plugged my PC back into the outlet, where the PC started up, all LEDS lit up and fans started, but monitor showed no signal.

I have tried taking out the cmos battery for 30 min, reseating ram, rreseating graphics card, switching ram slots, shorting JBA1 for 20 seconds, disconnecting from psu and holding power button for 2min, nothing has worked. Is there another solution?

During disassembly did you remove the 24-pin or 8-pin EPS? Did you try making sure they're fully seated or try reseating them?

What if I shorted something out on the motherboard?
