ASRock Riptide X570 won't power up

[der bastler]

Last May I built a new desktop PC with the following components:

• AMD Ryzen 7 5800X3D
  
• be quiet! Pure Rock 2 Black cooler
  
• ASRock Phantom Gaming Riptide AMD X570
  
• 64GB (2x 32GB) Kingston FURY Beast DDR4-3200 DIMM
  
• 8GB XFX Radeon RX 6600 Speedster SWFT 210
  
• 1TB Samsung 980 Pro M.2 2280 PCIe 4.0
  
• Intel Wi-Fi 6 Gig+ Desktop Kit, AX200 w/o vPro
  
• 600 Watt be quiet! System Power 9 CM Modular 80+ Bronze
  
• be quiet! PURE BASE 500 | BLACK case
  

It worked, for about ten months.

Out of a sudden it refuses to power up. The mainboard's RGB LED is cycling its colours. Power button is working (checked with a multimeter). CMOS battery is good. Shorting PS_ON brings up the PSU, and the POST LEDs indicate CPU and RAM not ready.

As I said, the system worked flawlessly beforehand.

Another oddity: after discovering the issue and checking above points I gave up and went out. On returning, I found the machine running, showing the UEFI HDD password dialog. The password was accepted, but the system was stuck with a black screen and I had to cut power.

I'd blame it on the UEFI and would send the board in. But perhaps there's someone who had a similar issue with an X570 board?

This leads me to issue #2: I bought an NVMe-USB adapter (JMS583-based) to check the SSD. Smartctl can read/parse the drive's information. Hdparm won't show any drive data. According to the log requests are ignored due to invalid operation codes. Unlocking the drive fails, too, due to invalid opcodes.

Since the power-up issue is not solved by removing the SSD I suspect the drive is sound and the adapter has issues? Anyone with JMS583 experience?

der bastler,

Unplug everything that plugs into the motherboard. Including the RAM and video card. (Not the CPU)
Fit a PC speaker if you don't have one.

The system should beep an error code sequence due to the lack of RAM.
If that works. Fit one stick of RAM and do it again.

Try the other stick alone too.

If the system can detect and bring up the RAM, it should beep an error code for no video card.
Once you get that fit the video card so you can see what's happening.

You should be able to navigate the firmware setup now.

If that works, fit the NVMe card.
It probably won't boot as the ever helpful EFI firmware will have removed the boot entry.
Navigating the firmware again counts as success.

I suspect a hardware problem. It may be fixed by 'wiping' connector contacts which is what removing and replugging does.

I've swapped RAM banks.

I've bought a new CR2032 and replaced the CMOS battery. Thanks to the layout I had to pull the graphics card.

Short-circuit starting the PSU still shows Post Checker Status: RAM bad, CPU bad.

I've notified ASRock support.

Anyways, I'll strip the sytem down and re-build it as NeddySeagoon proposed - hope dies last. The first and last time I had a dead mainboard was in 2000. The elkos of an Abit board leaked. Had to buy a new one, Abit pulled the too-late card. Since then "no Abit" and "all solid caps" are my minimum requirements.

der bastler,

CPU Good is a signal from the CPU. It won't come out of reset unless its own built in test works.
That's game over. No CPU - nothing else matters.

CPU bad on the motherboard could come from something else though.

The CMOS battery won't normally stop power up.
The first sign of needing to replace the CMOS battery is the BIOS clock runs very slow or stops.
As the battery fails further, the CMOS settings are lost and at power up, you are dumped into the firmware to fix it.
It's OK but inconvenient, to run without a CMOS battery.
