Gigabyte B550 not POSTing

[The Illusionist LK]

Hi Guys,

I have been using the PC I built back in 2021 with Gigabyte B550 Aorus Elite AX V2 and Ryzen 7 5800x with a UPS. Recently I moved, I didn't have a UPS with me and was using without a one.

Since I have been using without a UPS, I was getting some flashes on the display. During these flashes, sound was also stopping.

One day the screen flashed to black and never came up, and I thought it is a power issue, and it is static current got stuck or something. So, I removed everything, kept for a few hours, turned on, it came back to life. So I immediately went and purchased a new UPS.

 

Next morning, when I turned on the PC, again it went to black, and since then I have done the same thing I did earlier. I tried with a different RAM, different GPU, Flashed BIOS using QFlash Plus, and it does what it says it would do. When plugged in a USB stick and press the Q Flash button, the Q Flash LED flash for some time, PC Turns on and then flash the LED slowly. And then shutdown on it's own.

But it is still not POSTing,

When the power button pressed, Fans start to spin, but nothing comes up on the screen, no RGB.

 

Can you please provide some suggestion for me to test on this, before going for a new motherboard

Does the Mainboard has a q-led 

That indicate what the problem is? 

 

Furthermore does the Mainboard has a second 16x pcie 4.0 or 3.0 slot where you could plug in your gpu?
