[SOLVED] No POST Asus X470-PRO

[CheeseDogX]

CPU: Ryzen 5 2600x
Motherboard: Asus X470-pro
Ram: 32 GB DDR4 2333 Mhz
SSD/HDD: 1.5 TB SSD 4 TB HDD
GPU: Msi Vega 64
PSU: Corsair RM 750X
Chassis: Thermaltake Level 10 GT

I recently had to change out my CPU, mobo, and PSU, after having issues with all three. The mobo is an Asus x470-pro, CPU is a Ryzen 5 2600x, PSU is a Corsair RM750X. The mobo has LEDs on it, and they light up when I turn the PSU on, so I know the mobo is drawing power. The case lights and fans all come on when I hit the power button, but nothing comes up on the monitor. I don't have PC speakers, so I don't know if there's any beeps. I get a POST code of 00, which my mobo manual says isn't used by Asus. I know the monitor works, and I plugged in a second one just to be safe. I've swapped out the RAM, tried connecting the monitor with and without a GPU, reseated the CPU, everything I can think of. I was getting ready to RMA the mobo, but I figured I'd see if anyone here had any other things I could try.

Best list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:

You should breadbaord the system and then work with bare minimums, i.e one stick of ram and the GPU on first slot of board and OS drive.

Might I ask why you had to change the parts listed above? What were the make and models of the parts prior?

I rewrote the specs above. My old mobo, an Asus prime b350 plus, died on me. So I bought this mobo because it would be compatible with the Ryzen 1800x I had. Then I bent the pins on the CPU. 😕 I tried fixing it, but they were too messed up. I don't remember what the old PSU was, but the wattage must have been too low, because I couldn't get it to power up right.

I'm not really familiar with breadboarding. When you say bare minimums, do you mean that I should unplug the SSD/HDD? The CPU has a GPU, so I've tried running the system with and without the GPU.

Make sure all power cables are attached to the motherboard and GPU. You MUST have a GPU installed and connected to the monitor to get any sort of display output. Install a single stick of RAM in the proper slot(see manual). Clear CMOS. Hopefully this will allow you to enter BIOS. Once in BIOS reset to defaults.

Thanks for the advice, drivinfast. I did what you suggested, and at the same time I tried something which the Asus website suggested, which was to remove the CPU and use contact cleaner on the board. Once I reseated the CPU, I was able to boot up normally. So it looks like I'm up and running again!
