Question ASUS TUF Gaming S570-Plus (WiFi) Won't Boot

[GeekyOne]

My new build with this motherboard won't boot. The cool multi-color LED under the chip-set fan lights up and cycles through various colors when plugged and stays lit. When I power on, the troubleshooting LEDs cycle through DRAM -> CPU -> VGA -> then gets stuck on BOOT (yellow green). Fans all run and the CPU cooler pump LED lights up. Keyboard is activated/detected (Num Lock and Function Key LEDs light up). Monitor power LED stays amber, but if I press it's power button, it says "no signal". I never get a BIOS splash screen or any text showing up to go into BIOS setup. The sticker by the RAM ends in 2607, which is the BIOS version that should support the Ryzen 5600X as indicated in the support URL below. I tried resetting the CMOS both ways (including pulling the battery). I tried disconnected all peripherals but the mouse, keyboard, and monitor. I tried swapping in 2 different graphics cards that worked in my other PCs. I also pulled the 2nd stick of RAM leaving only 1 in the grey A2 slot. The only thing I didn't try disconnecting was the NVME SSD in the 2nd slot as I'd have to remove the motherboard heat sink which has an adhesive to stick to the SSD.

Make sure you have a GPU and plug the monitor display cables on the GPU.
Put the ram on slot A2 and B2.

If you dont have a compatible cpu, try to reach out a friend that have 3000 series cpu/apu and flash the latest bios, otherwise you need to ask to update the latest bios on where did you buy the motherboard.

This is the latest bios for your motherboard

As Koekieezz has said, you havnt listed a GPU? The 5600x does not have integrated graphics so you will need a GPU in order for it to display.

Yep, tried 2 different GPUs and even swapped out the one that required 2 PCIe power cables for one that powers off the PCIe slot, both connecting to the monitor by HDMI. I even tested on my old 1080p monitor instead of hooking it to my 4k monitor to avoid any video problems. Since it passes the onboard video LED, it seems like it is not video related, but boot related.
I bought the MB, CPU, and RAM all from Micro Center way back in January and February (didn't have time to assemble until now). I seem to remember a program where ASUS would lend customers and older AMD CPU to flash the BIOS, but 2607 BIOS is supposed to support Zen 3. Do you think they'd let me swap my motherboard for a newer one?

 

[Koekieezz]

Updating the latest bios could help, or swap it with another variant that works.

 

[kurdtnz]

As you said, the sticker says 2607 which is the correct BIOS for your cpu. But can you please confirm what cpu you actually have, you've listed both the 5600x and 5800x?

 

[GeekyOne]

The first GPU I tried was an XFX Radeon HD 7870, then swapped it out for an old PNY GeForce GT545 to eliminate any possible problem with PCIe power cables.

 

[GeekyOne]

It's a 5600X (I'll correct the original post).

I tried swapping DIMMs into slot A2 and while pressing the keyboard, saw some the monitor splash screen briefly flicker every time I hit delete, so decided to try another HDMI cable, one that seemed even thinner than the other one. Wow - now it works and goes into BIOS!
So much for "DYNEX High-speed HDMI Cable with Ethernet" - that's some Best Buy brand trash that is going into the trash!
Apparently the yellow green BOOT troubleshooting LED stays on while you're still in the BIOS screen - I guess it doesn't go out until you have some bootable drive installed (like an operating system).
