Aurora R10, system board failure?

What is the back story . . . which Alienware do you have? What were you doing right before it stopped working? What makes you think it is a system board failure? The more information the better we can help.

OP had followed a previous thread

“My Aurora R10 (Ryzen 7 3700X) does not boot and the power button flashes 2 then 1. The manual says this is motherboard related. I changed the motherboard with a new one, and still same issue.”

yes, I know . . . still trying to extract information. I don't want to be making assumptions and guessing.

It’s a r10 and before I was playing on it and shut it off by power button because my monitor started acting up and I left it alone woke up and it started acting like this also it’s a 2,1 flash white light 

Monitor starting to act up could point to a video card failure.

Make sure your graphics card is securely seated and locked in the slot.

Disconnect power from the PSU, hold the power button in for 30 seconds, take out all for your RAM modules, reconnect power and try to boot with no RAM installed. The diagnostic blink code should change to a 2-blink pattern if your motherboard is functioning properly.

@Vanadiel​ no not that but smart and thank you it’s just the monitor having a issue

Very peculiar that a monitor issue would cause a 2:1 diagnostic blink code.

@ProfessorW00d​ My Aurora R10 (Ryzen 7 3700X) does not boot and the power button flashes 2 then 1. How it all happened. I changed the RAM to a one 32gb stick and from there it wouldn't boot up. Heard a spark and white light trying to boot and after it won't even try to power on. Only reason I see the flash is because I press power button at the same time as I press the back test button. Other than that the test button is the only thing that powers the Fans and GPU .... I changed everything back and did all the steps on here and to no resolution 

@Spaniard848​  A spark flash is never good news. Try taking out all of your RAM. Boot up with no RAM installed and see if you get the 2 blink pattern . . . no RAM detected. If you do, it might mean that your motherboard is still functioning.

It didn't change anything 

Funny thing after all that the PC tried starting up without having touched anything 

@Spaniard848​    hold in the power button for 30 seconds to clear CMOS. Then see what she does.

Did that 2 times got Same results 

@Spaniard848​   get a good light source and see if you can find where the spark was initiated. Any burn marks or damages components on your motherboard? The outlook does not appear to be good.
