[SOLVED] Stuck on white LED（VGA Q-LED）and NO POST

[-M0M0-]

Hi guys,
so I build my first PC and I'm having an issue with it. Stuck on white LED（VGA Q-LED）and NO POST. This is the whole thing.

When I finished the installation for the first time, everything was fine and Windows was running normally. But when I was using it the next day, the computer suddenly crashed. When I restarted the computer, No display on monitor, VGA LED solid white, Fans spinning, no weird noises etc. So I tried the following (no help):

• reseating the GPU
• reseating the ram (1 only or 2)
• reconnecting the pcie power cable to make sure it wasn't loose
• reconnecting the display port cable to make sure it wasn't loose
• trying a different pcie power cable
• trying a different pci slot
• trying an hdmi cable instead of using display port
• checked for bent/dirty pins
• short the cmos pins to clear the CMOS

I checked my GPU on another computer and it is working properly. So I think it may be the problem of MOBO. RMA and got a new MOBO. Unfortunately, after the installation is complete, the VGA light is still on. Next, I tried to keep only the CPU, RAM and GPU, I can enter the BIOS after booting! ! ! ! The good times didn’t last long, and the BIOS quickly stuck. After restarting, the VGA light stuck and I don’t know what to do.

Appreciate any help i can get.

System Components Currently Installed:

• MOBO：ASUS ROG STRIX B550-I GAMING
• CPU: AMD Ryzen 5950X
• RAM: Corsair DDR4 3600 MHz 16GB*2
• Heat Sink: NZXT KraKen Z63
• GPU：ASUS TUF 3070
• PSU: PHANTEKS AMP 1000W
• SSD: Samsung 980pro NVMe M.2

VGA debug LED, for the most part, means there's issue with GPU.

So, try with different GPU and look if issue remains.

Sadly, since you went with Ryzen CPU and not Intel CPU (non-F) or AMD APU, you can not connect your monitor to MoBo and use iGPU, built-in those CPUs.
In that sense, APU or Intel CPU (non-F), are better since when there's issue with dedicated GPU, you have backup iGPU to use.

tks, I tried a new CPU and a new MOBO, and finally found that it was a problem with the CPU. RMA and waiting for a new one.
