[SOLVED] PC won't POST ?

###Troubleshooting Help:

What is your parts list?

Motherboard: Asus Prime B450M-A

CPU: AMD Ryzen 5 2600X

GPU: XFX Radeon RX 570 8gb

PSU: EVGA 600W 80+

Ram: 4×4gb Viper 2666MGhz


Describe your problem. List any error messages and symptoms. Be descriptive.

I originally have a Ryzen 3 2200g with the stock cooler for about a year. I decided that it was time for an upgrade so I bought a Ryzen 5 2600X and a Cooler Master Hyper 212 Evo. After a very annoying install process, I started up the pc. All the lights came on and all fans are spinning but nothing is coming up on my monitor and my other peripherals (mouse, keyboard) aren't lighting up either. I thought maybe I installed the cpu incorrectly or maybe it was doa so I reinstalled my old cpu. Same thing occurred. No post at all. I've tried troubleshooting myself by checking the ram and gpu but to no avail. I'm honestly at a loss right now and I'm considering that maybe something is wrong with the motherboard or power supply. If anyone has any ideas, let me know because this is a real pain in the ass.

List anything you've done in attempt to diagnose or fix the problem.

Used different ram and checked different ram slots, unplugged and plugged back in cpu and 24 pin connectors, tried using my old cpu, cleared CMOS, and tried booting without my gpu connected.

recheck all the power to the motherboard/gpu?

If it worked fine before the upgrade it's not likely a motherboard issue, unless you somehow damaged it during the upgrade process (you didn't do it on a carpet with socks on, right?).

Double check the PSU is properly hooked up to both the 24 pin connector on the right and the 8 pin on the top left. Also try assembling it outside of the case, on top of the motherboard box or another non conductive surface. It's possible something may be shorting the motherboard.

If it still doesn't work you'll need to hook up the debug speaker to the motherboard to see if you get any debug beeps (if your board came with it it should be in the box, otherwise they cost like $2 at any pc store).

I unplugged and plugged back in the 24 pin and the 8 pin connector. Still nothing. I'm going to take it out of the case later in hope that it really is just a short.

I checked. I'm not sure about other mobos but it's always a pain to get those plugs out and back in.

I just took out my mobo and set it up on my mobo box. Its posting now HOORAYYYY!! I dont know what the problem was though. Was it something in the case shorting it out? And how do I fix that?

Make sure you install the motherboard on standoffs and don't screw it directly to the case's motherboard tray. Also make sure to only use the correct screws, and that you're using a grounded cable for the PSU (the power plug should have three prongs, not two). If it still doesn't post in the case, you will need to connect that debug speaker I mentioned earlier. You would disconnect everything except the motherboard, PSU, CPU and cooler and test to see if it starts up and beeps. If it does, add each component one by one and try to boot each time. As long as it beeps (or posts) it means it's fine, once it stops you've found what's causing the short.
