I'm having an issue with my Asrock X470 Taichi and I hope someone on here can help me... I've had this motherboard for about 4 months and it has been working fine. Yesterday there was a power outage, and now the motherboard won't post.
When I started it after the power outage, I was getting 5 short beeps. After looking that up, it seemed related to the graphics card. It also conformed to the Dr.Debug post code, which was d6. After I looked, the fans of the graphics card were not spinning when power up the PC. I decided to take the graphics card out (R9 Fury) and put it back in, and the same issue remained. I then decided to reset the CMOS by pressing the reset button in the back. I stopped getting any beeps, and now I get post code either 76 or 7b, don't know which it is. I have a link to a video later.
I thought my graphics card died at first, so I took an old HD 6850 and stuck it in there, and, the same error occurred. But on this card, the fans do spin at least, but, the errors are the same.
I then removed all USB devices, SATA devices, and my sound and graphics card. All that remained are my two NVME drives. I then reinstalled my memory and my CPU, reset the CMOS by both pressing the button and removing the battery, and the same issue occurred... Basically it starts posting, and when it reaches 76/7b, it stays there indefinitely. I left it on for an hour. So I have to manually shut it down by holding the power button for a few seconds. I should also mention that posting without RAM gives the proper error code.
I have recorded a video of the error code, with only CPU, RAM and my 2 NVME drives connected;
So my questions;
What is the error code? 76 or 7b?
What does the error code above mean? (CPU? Motherboard? Something else?)
How do I fix it?
