hello computer

there are no red lights anyware but the debug light next to the cpu is on but i dont think it is the cpu because thats the first light to turn on. all of the fans are on including the gpu and they do not turn off its like it is on but there is no output. with the case connectors they are just one brick of connectors so i doubt that those are the problem but it pu in a adapter they have and tried putting them in and it did not work. im thinking this is a bad motherboard

yeah i have already tried that.

I just built my first pc and have had trouble with the computer. I have a msi b550 pro vdh wifi motherboard, a amd ryzen 3 3100, 16gb tforce vulcan z ram, 1650 super 4gb. when i turn on the computer everything is on lights and fans but there si no post and the ex debug light is on. I have tried to update the bios but they either do not seem to work beacuse the light blinks then goes solid and never turns off.
