Asus Prime x570-pro locks up at post...

[Devgear]

As the title says, I can't get past the ASUS logo screen with the prompts to enter the bios.

I just put together an Asus MB combo with a 3900x on top of it. System Led lights all pass and then boot light is steady green. I'm assuming that is good, right? Asus screen comes up, but I never get the system hardware check screen, even upon cmos clearing... it just always goes to Asus logo screen and stays there and all keys are unresponsive to get into bios.

Build specs are:
MB - Asus Prime x570-pro
CPU - Ryzen 9 3900x
MEM - 32G Fury @ 2133 (recycled from my past build and will upgrade)
VGA - GTX 1060 6G
HD - 1TB WD-NVME

Any ideas or advice would be greatly appreciated. It's my first time to build with AMD.

Thanks,
James

Remove the WD and one stick of RAM at a time. Does this still happen?

Disconnect the HD

Hi Guys,

Thanks for the advice... as it turned out, it was a RAM compatibility issue. (previous was 2 - 8G@ 2133 and 2 - 8G@ 2400) I picked up 2 new sticks of 3200 Fury and it posted right away. Whew!
I installed a Windows cloned M.2 drive and booted into Windows with no issues. Like it couldn't have been an easier Mobo and CPU swap... aside from the first little hiccup.
Cheers
