I have the same problem
asrock z87 extreme 4
ram 8g 1600
cpu i5 4570
gpu gtx1060

After using this motherboard for a one years, this problem happened.
When I turn off the power (turn off the standby key) and restart the system, I encounter code 00.
It's a strange problem.
I didn't have such a problem with Asus motherboards.

The only temporary solution:
I turn off the system and press the cmos clear key.
A few moments later, the system turns on by itself and the code 00 disappears.
This is a temporary solution.
After a few days, code 00 occurs again
Support has not given me any solution so far

A code 00 usually means, a defective CPU.
Remove all hardware, and check the CPU socket pins, than mount the CPU cooler, but don't tighten it, and 1 memory module, and of course both PSU cables, wired USB keyboard and mouse, and a monitor.
Or use the tech support form https://tw.asrock.com/events/tsd.asp
And check the spam folder for replies
Kind Regards

Hi there,

4 years ago I have build my system using below equipment:

- MB: Ashrock Z390 Phantom Gaming 9
- CPU: Intel i9 9900K
- Cooling: AIO Cooler Master
- Ram: 32gb ram DDR4 Corsair Vengeance LPX 2400Mhz
- PSU: Corsair CX750M 750w
- GPU: (Updated) Radeon 6700 XT
- M2 1TB drive
- Seagate 3TB HDD
- 2 x 512 SSD random vendor

Yesterday, I have turned my PC off (Shut down) as usual and today when I tried to turn it back on the whole PC is dead with the code displaying OO.

Troubleshooting i have done so far:
- cleared CMOS (with the method provided on this forum)
- removed parts (3 x ram, GPU, drives)
- checked PSU with shorting method - works

My question is, what else I can do to fix the issue of to troubleshoot more?
CPU was not overclocked and it was working fine for the past 4 years.

Any help would be awesome. Thanks
