Hi all - stuck on my first build and wondering if anyone had any tips.

Parts:

ASRock AB350 Pro4
AMD Ryzen 5 1600
G.SKILL Flare X (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2400 (PC4 19200) F4-2400C15D-16GFXR
GeForce GTX 1060 6GB 6 GB Mini ITX OC Video Card
SeaSonic - 520 W 80+ Bronze Certified Fully-Modular ATX Power Supply

The RAM is explicitly compatible with Ryzen, as noted here (https://www.amd.com/system/files/2017-06/am4-motherboard-memory-support-list-en_0.pdf), so I don't *think* that should be an issue.

I'm geting the 5 short beep "problem with CPU" code in the following configurations:

1 stick of RAM in slot A1, with video card in
1 stick of RAM in slot A2, with video card in
1 stick of RAM in slot B1, with video card in
1 stick of RAM in slot B2, with video card in
same as above (each of 4 slots) but with video card out
1 stick of RAM in each of slots A2 and B2 (both RAM sticks in), with video card in

However, when I remove all the RAM (with or without video card in), I get a boot loop - no beeping, just constant rebooting with fans spinning up and down. Which makes me think maybe the RAM is the issue?

At no point am I seeing video output, over either motherboard VGA or motherboard or video card HDMI.

Does anyone have any ideas? I'm making sure I've got the CPU and motherboard main power seated well, as well as the power to the video card directly, and I reset the CMOS in between each of these attempts. This is a scratch build, so I unfortunately don't have the parts hanging around to swap out e.g. the PSU to see if that fixes anything.

I'm sort of at a loss here - thank you in advance for any ideas!

mainboard doesnt have working video output with your cpu

5short beeps doesnt have to be cpu, mine mobo can 5beep from gpu or sound card (pci-e)

your issue maybe with CSM module, try to update your bios with another GPU (in pc shop they could do that for you)
