4 motherboard led issue
sgar7
✭
I am trying to build my first PC. When I plug in my Asus B450-F to my Seasonic Focus Gx-750 and turn it on the Asus logo lights up but the 4 leds on the motherboard don’t. In the manual it sounds like all 4 lights should light up. Can anyone help?

Greetings,
They're visual indicators for the POST test. They should light up and go out for each device that passes. They may not light up at all, but it's odd that you're not seeing any activity. Verify your 4+4 8 pin CPU power cable is attached. Without this, it'll hang prior to CPU initialization and you won't get anything. If you had a QCode reader, you'd be sitting on a 00. -
Thanks,
The 4 + 4 8 pin cpu power cable is connected as well as the 24 + 8 pin cable. There is one stick of ram in the 4th Dimm and the CPU cooler is plugged in. Could there be any other reason the lights or the computer is not booting?

When you say you turned the PC on, did you mean you turned the switch on the power supply, or used the power button on your computer's case? Just flipping the switch on the PSU won't actually turn the system fully on, you have to plug in your front panel cables on your case and use the power button.
What processor are you using, and do you have a GPU installed as well? -
I have flipped the switch and pressed the power button. Will holding it work? I am using 3700x and 5700xt.

When you press the power button, does anything happen? Do any fans start spinning or any more lights turn on?

I just put the system back together and pressed the power button and lights turned on and fans started spinning. I plugged in the hdmi to the motherboard port, I got a grey screen for less than a second and then it turned black again. Should I move the cord anywhere else?

Monitor needs to be plugged directly into the video card, not the motherboard.
