Howdy!
I built a Custom liquid-cooled Gaming PC and when I first powered it on, it wouldn't post. I checked the motherboard Debug Leds and it had a solid red CPU Light and a blinking red Dram (Which I have read is normal during memory training on am5). After trying all the troubleshooting steps (and referring to the steps on the README: How to respond to a no POST or no power up situation) I could think of I was led to believe that either the CPU or Motherboard was not functioning correctly. Using AMD's excellent RMA service I was able to relatively swiftly get my potentially faulty 7700x replaced with a brand new one, but I was still receiving the same no post and solid CPU light, after trying my troubleshooting steps once again I decided to try and get the motherboard Rma'd through Asrock (I probably should have tried to get it replaced or returned it and gotten a refund via Newegg, but I did not choose to do that at the time and I am now outside of my window to do so). I received my replacement Motherboard from Asrock about a week about and while it was not in retail packaging and it did have one of the SSD thermal pads pealed (which was the same one I peeled for my SSD on my original board), the Serial number is a different from my original board so I assumed they just sent me a working open box or repaired replacement board. Unfortunately, even with my replacement motherboard and cpu, I am still getting the same issue. I have listed the troubleshooting steps I have taken Below. I feel I have Isolated the things that could theoretically be wrong with it down to the Motherboard CPU and RAM or perhaps somehow the previous motherboard had something so wrong with it that it broke my original and replacement Cpu (which feels unlikely), Given that I have RMA'd both the Cpu and Motherboard it would lead me to wonder if something is wrong with the ram, however, I am still getting the Red CPU debug light when I try powering on without ram. Any and all help would be greatly appreciated.
Problem: The Computer gets power but does not post, Debug Led's display solid red Light
I have tried:
Turning it off and on again
Reseating Powercables
Reseating the CPU
Reseating Ram
Both Ram sticks individually
No Ram sticks (the blinking dram light does not turn on in this case)
No graphics card (using igpu)
Removing the SSD
Testing the Graphics Card in another system showed it was still working although I'm not sure to what extent as I was not able to stress test it.
Tried with nothing but the motherboard power cables plugged in (2x8 pin CPU, 24pin mobo)
Tried Different monitor's and Different cables
A different Power supply (Evga 700 Br)
6 Different wall outlets on 3 different Breakers and 2 different power cables (both of which were tested working) both with and without a UPS on all of them
Clearing CMOS (both through the header and through taking out and putting back in the cr2032 battery)
Updating Motherboard Bios to the most recent (2.10) Using Bios Flashback Feature (only attempted once on each motherboard, appeared to be successful both times)
Tested the power supply on different PC (ryzen 7 3700x, rx 5700 xt) and ran a stress test with it and it still appears to be working fine.
Specs:
Cpu: Ryzen 7 7700x
Mobo: Asrock B650 Livemixer
Ram: 32gb Gskill flare x6 6000mhz cl 36
GPU: GeForce RTX™ 3080 GAMING OC WATERFORCE WB 10G
Ssd: Solidigm P41 Plus 2tb
Psu: Maingear ignition 1200w Platinum
Case: Lian Li Lancool 2 Mesh
