White LED Debug on Mobo

[FTL_Error404]

Hello guess.

So I'm a newbie on pc building, and a few days ago I assembled my new pc. I bought every part separately brand new.

I had no problems at first. Dloaded all the drivers and a few games to test it. Didn't made any changes on the bios because is not showing properly but overall the pc was running fine until...

I had my first white led on vga and I had no display so I shut it down from the start button. A few hours later I've attempted to turn it on again and it was fine.

The next day happened the same thing but I had the CPU light on. No display again.

Today I left home with the pc dloading apex and screen was close. Few hours when I came back the pc was on sleep move and when I pressed the power button I've had a boot white led until now...

Every time I had a white led on my mobo no matter which on, my screen was acting the same. No display and it was turning on and off, not responding on any button. I tried to turn the off from the button but it was going on and off all over until I plugged the cable from the screen out.

 

Specs:

CPU: Ryzen 5 2600

RAM : 2x GSkill Ripjaws 8GB 3200Mhz

GPU: AMD RX 580 8GB

MOBO : MSI B450-A PRO

PSU : Seasonic Focus M12 Bronze 520

SSD : Patriot 240GB

My screen is an 27inch Damsung LCD TV back from 2006-7 (if I remember right). 

 

Any sort of help would be appropriated

Thank you!

 

On the photo is how the bios is showing up.

I pressed the reset and the pc booted, pressed f2 and it's running fine again.
