X670E PG Lightining stuck on boot when restarting

Hello guys.
I have a strange issue with my system since I got it two months ago. I have been waiting for new BIOS versions to see if they fix this, but so far using the latest beta (1.14) I have the same issue.

Basically, when I restart my system, it will be stuck with CPU/DRAM led on and it won't go past that even after several minutes. First I thought it was the XMP settings that were causing this issue, because they keep being reverted to 4800MHz when that happens. But I noticed that even with default BIOS settings, upon a restart it can get stuck on that was well after a restart.
The strange thing is that if I manage to apply XMP settings and I DON'T restart, the system is fine and the RAM keeps its XMP settings and the boot is fine. As soon as I restart it gets stuck and I have to force shutdown or clear CMOS.

I have tried increasing every possible voltage, disabling Power Down Mode, several different settings and nothing helps.
I have tested each of the RAM sticks and they are fine.
The system is perfectly stable at XMP settings when running stability tests or intensive games and I only shutdown and don't restart.
I have reseated the CPU to check for bent pins, everything is fine.

Note: sometimes when restarting it will not be stuck with leds on but I notice that the system shutdowns and then starts again (because of the power supply "click" sound). When it starts up again, if I go to BIOS, the XMP settings will be "saved" but the speed is not applied and will be 4800MHz.

Any help will be appreciated. Thanks.

I don't, I have a Noctua NH-D15.
I also saw some reports about the pressure of the cooler causing some issues and loosed the pressure already, but had no success.
I also checked for bent pins when I did that and everything is fine.

I don't think it's a hardware issue, since I only have problems when restarting the system. If I only shutdown and turn on, everything is fine and stable...I'm guessing I need a new BIOS version to fix this but wanted to see if there are more people with this.

I also tired beta bios 1.14.AS06. Same problem during reboot.

Unfortunately the MB started having issues booting up from a cold boot, so it seems there is a defect. I was not even able to boot my system with Default BIOS settings.
I believe that anyone that has this kind of issue should consider it a hardware defect and not bad BIOS (as I first suspected).

I have RMA'd it and I'm waiting for AsRock response...

Up until today, I was not having this issue. System has been running stable since mid-December. Then I updated the bios from 1.09 to 1.18 and any time I restart now I get CPU and DRAM error LEDs. I'm going to try and revert back to the pervious BIOS and see if that corrects the problem.
