Built my PC and it worked fine. Got windows running and used it for about an hour then screen went black and it will no longer post.
When I turn on the PC the lights and fans turn on but the screen stays black. (Not a monitor problem I checked) the CPU and dram red LED lights come on for a second then the boot light comes on and stays on. Any idea how to fix this?

Build details:
ASRock x570 phantom gaming 4
Ryzen 7 3800x
Gigabyte rx 5700xt 8gb
2x8gb Corsair vengeance ddr4
Corsair rm750x fully modular 750w psu
Wd blue 500gb m.2 SSD
Seagate 4tb hdd

ok reset the pc

remove power plug from wall socket
open pc case and remove the small coin sized cmos battery from mother board
press and hold the pc case power button for 30 secs
refit the coin battery
plug back into the wall
try booting the pc now
remember this first boot after a reset may take 2-5 mins so just go make a cuppa

Going to try and rebuild outside the case to make sure nothing is shorting. If not I have the replacement plan on the motherboard so I can get it replaced.

Hey,

The same thing literally happened to me on that board with 3600x. Did you figure it out?

I realize this is really late but I just "solved" it. At first I replaced the motherboard but there was no change. I then sent the cpu back to AMD for an RMA. It just got back to me now and the pc is working.

Had the same problem, first I got a blue screen of death, rebooted, worked fine for a couple seconds, then PC locked up. Rebooted again and that Boot light came on, Tried resetting cmos, changing mem slots checked all plugs and connections. nothing fixed it. A few weeks ago I upgraded the Junk HP memory that came with the PC to Corsair Vengeance LPX 2x16 GB 3200 MHz. Worked fine until today. after trying all kinds of stuff I swapped back to the 16GB HP memory and it booted up just fine.

Have the same issue. Recieved the motherboard + AMD Ryzen 5 1600. I have one stick of 32GB RAM.

When I hooked up everything the computer worked for several hours. I installed Ubuntu 20.04 normally, everything worked. After returning to the PC several hours later the display was blank. Upon several resets I checked the MB and found this red BOOT led.

I sent a request to the seller, I will probably have to return this MB + CPU. But I hate going through this hassle if it can maybe me solved another way.

Attempted so far:
- removed all hard drives
- tried with another PSU
- switched RAM to different slot
- tried another 4GB DDR4 ram stick in multiple slots from another computer
- tried removing the cmos battery for 30 minutes
- tried re-seating the CPU - upon removing the heatsink I can say that the thermal paste was perfectly applied the first time

Any other ideas maybe?

And I am really curious what could have caused this. To have everything work perfectly and then just dies. Maybe something overheated and permanently damaged the CPU or MB? But why a BOOT LED, why not a CPU LED. So strange...

Replying to myself.

Tested CPU on another motherboard. Also doesnt work.

Tested another CPU on this motherboard and it works.

Verdict, CPU died, will be returned. Defective I guess...
