PC Won't Boot At All (Tried Common Troubleshooting)

Turker

Motherboards:

B450 Tomahawk MAX

crosshair 8 hero

Power supplies:

Thermaltake 500 watts

Corsair rmx 750x

CPU: Ryzen 5 3600

GPU: GTX 1080ti gaming x trio

Case: Lian Li O11 Dynamic XL

I recently switched from my old motherboard (B450 tomahawk) to my crosshair 8 hero and the LEDs on the board turned on, but nothing else. I tried every possible solution I could think and every solution I got from reddit for it, clearing cmos using battery, updating bios with flashback etc. I started building it outside my case by just plugging in the motherboard cable, cpu, and pcie cables. But the fans, gpu, or really anything other than motherboard lights didn't turn on. 

Then, I went out today and bought a Tomahawk max, which also didn't turn on. I just did the paperclip test with both of my psus and both past, I'm really not sure what to do now...

Could it be a cpu problem? I just got this cpu after I bent the pins on my 3900x, literally got it yesterday, so I'm not sure if that's the problem.

Maybe my gpu broke somehow?

Is there some special connector for the o11 dynamic, all I did was use the front panel wires to use the power button after shorting the two power switch pins didn't work.

Any ideas?

It's most likely not a board or PSU issue since you've tried multiples of those already. I'd say likely cause is the CPU, but it's hard to say for sure. Have you made sure the 3600X also doesn't have any bent pins, and did you make sure the CPU fan was plugged into the CPU fan header?

Run through this guide if you haven't already just to be safe and make sure you covered all your bases: https://community.microcenter.com/discussion/2818/tech-article-how-to-troubleshoot-a-newly-built-pc-that-will-not-post-boot-power-on

I just got this cpu yesterday, there was one bent pin but I managed to fix it, the cpu goes fully into the socket too...I made sure the cou fan was plugged in though yes.

Also the new motherboard shows no signs of life, no led lights or anything. Could it be busted? I did pick it up open box from my local micro center

Greetings @Turker

The Crosshair board would of had a power button on the board. So you turn on the PSU and the board gets standby power, but you press the "Start" button on the board, and nothing happens? Pull all your modular power cables, try to power it with the 24 pin only connected. Don't mix modular PSU cables.

Tried with just the 24 pjn, the start button doesn't do anything

@Turker

Nothing at all? You're not hearing any sounds besides the button? No clicks from the power supply as an example? And confirm you disconnected the cables from the power supply as well if they're modular.

The psu fan doesn't turn on, no sounds from mobo

Have you tested the motherboards outside the chassis on cardboard?

Turker

I'm only tearing outside on my case box.

I'm only tearing outside my case using the case box

Seems unusual. It's possible that the CPU is shorting the board out, but you should see something momentarily. A flash of light, a quarter turn of a fan. You can pull the CPU and try powering it on. It should power on without a CPU and sit on code 00.

I've tried that, same thing no q code though. Just led on the Mobo turns on. I'm very confused as well haha

@Turker

The LED's turning on is just standby power, but it won't power it. Which sounds like a dead board. And you're on cardboard, you're not sitting it on the antistatic bag, correct?

Nope it's on a cardboard board. I went and bought another board whi h had no LEDs on. What are the chances in having two dead boards in a row? (I did buy this one used from microcenter)

@Turker

So the other board with the same PSU, isn't getting standby power. It's hard to say. You've tested two boards and two power supplies. Pretty unlikely that you're having the two out of four devices are dead either way. Keep in mind with the paper clip test on the PSU. All that tells you is that the PSU is functional, it won't tell your if one of the rails is dead, but this would still cause no power. Make sure you're testing both PSU's, even if they pass the paperclip test.
