[SOLVED] Monitor suddenly turn off and say "no signal" and ez debug led cpu light on

[victor_vu]

Hey guys I have a problem with my PC.

I'm using my PC normally and the monitor suddenly turn off and say " No signal". I started investigating the motherboard, and i see the ez debug led cpu light on. I can only push the reset button, after the system restart, it worked normally.
It somtimes happen, about 2 times/ month.

This is my specs:
MOBO: MSI B450 Tomahawk
PSU: Cooler master G750M
CPU: Ryzen 5 2600
VGA: Power color RX 580 8Gb
Ram: G.Skill Trident Z RGB 16Gb 3000 Mhz (2 x 8Gb)

I builded my PC 2 months ago. All the parts is new 100%, except the VGA. I bought an old VGA.

Any help/suggestions would be greatly appreciated.
Thanks.

Check that the video cable is fully and firmly in place.

Likewise make sure that the video card is fully and firmly in place.

Swap in another known working video cable.

Look in Reliability History for error codes or warnings that correspond with the times that the monitor turned off.

My problem was solved. It seem like due to GPU driver.
I use DDU and perform a clean install driver. And it run very good
