I just finished my new build ( second of all time) and the computer won't post with ez debug cpu light turned on.
Both motherboard 24 pin and cpu 8+4 pin are connected in both PSU and motherboard.
The motherbord ez debug cpu light is solid red and no output to display with HDMI cable connect to GPU.
All fans are spinning, and the case and mobo leds turn on. Also, rest of the debug lights turn on for a second, but only the cpu stays on.
Build is all new, except for the GPU:
I tried reseating the ram, plugged it one at a time in any of the positions ( both of them, i got 2 sticks). The ram is working as i tried it on another pc i got and it booted.
Triple checked the PSU connections for ( both 24 pin for motherboard and 8+4 for CPU). Not sure if cables are working, but i swapped the cpu ones around and still nothing)
I also uninstalled the nvme drive ( wd sn 850 seated in first position). no success.
Removed the cooler, triple checked the CPU pins, nothing is bent and i see no damage or thermal paste in the motherboard socket.
I also reset CMOS by removing the battery for 1 hour while psu is unplugged and shorting jbat1 connectors multiple times.
Updated BIOS with flashback ( it took about 5 minutes while both usb led and mobo white led flashed, after which the system restarted) so presume this was a success.
Motherboard has "amd 5000 series desktop ready" printed on the box as it's a model launched late last year.
I have no other CPU or motherboard with which to test if CPU or motherboard is DOA.
The cpu heats up if i leave the system running even with the red cpu light on.
I also tried powering it up without the GPU, again, only CPU light turns on.
Only thing i did not do is reamove the MOBO from the case, but i unplugged every other component ( SSD and case connections).
Any other suggestion is appreciated as i am running out of ideas .
