Second build ever, so trying to learn the proper way to debug these things.

SYSTEM:
Motherboard: MAG B550 Tomahawk
CPU: Ryzen 7 3700X
Graphics Card: XFX AMD Radeon™ RX 5700 XT 8GB GDDR6 THICC III Ultra
RAM: 2X 8GB Corsair Vengeance 3200 DDR4


SYMPTOM:
Fans turn on but the EZ-Debug CPU light is on and nothing appears on screen.

ATTEMPTED:
  1. Reseated CPU applying pressure as I activated lever
  2. Reconnected CPU 8 Pin cable
  3. Removed all RAM except in DIMMA2
So far all of this has yielded the same result. Would love to learn what else may work. Thank you all for the support, I am excited to get this build up and running!

Can you try with a different graphics card? I only say that because I know the CPU LED is on, but that can sometimes be a bit of a misnomer. I also say that because aside from your graphics card, you have an extremely similar setup to mine, bar the graphics card.

I don't have a second graphics card, but I tried just pulling the graphics card and got nothing.

Using an EVGA 750 B5.
Just tried pulling the motherboard out and reseating all the components. Still getting the CPU debug light.

Here is my full build:

Thank you again for the help, this is rather stressful with $1500 worth of parts just sitting here! I don't have access to a card for testing right now. Might be able to borrow a card from work later today. I will try to make that happen.

After Reseating the graphics card for what feels like the 100th time i got it to so the boot light is showing on the MOBO. Now going to reinstall in case and see if I can get things moving.

Will update with results!

I AM POSTING THIS FROM MY NEW PC! I think it must have been a graphics card issue, as well as being patient and letting the system boot all the way. For others finding this make sure to let those LEDs settle before shutting the system back off. I got nervous and powered it down too soon I think.

Hey you're more than welcome. I know that the B550 Tomahawk has one or two niggles with the initial BIOS when it comes to graphics cards, mine will give 1 long beep and 3 short beeps if my monitor isn't switched on, believe it's a DisplayPort issue that has been resolved with later BIOS versions.

But really glad you've got the system up and running!
