What code do you see in the Dr Debug display when the PC fails to start?

What CPU are you using, and what UEFI/BIOS version does your board have? Some CPUs require specific UEFI/BIOS versions to operate.

Dear Kknd,

 

Thank you for contacting ASRock.

 

Regarding your case, we provide somesuggestions to try:

1.     Clear CMOS to load BIOSdefault.

Please checkuser manual p28 to clear CMOS.

2.     Only install CPU and one stickmemory to check if the system can boot into BIOS properly.

3.     Please try to install one stickmemory at A1, B1, A2 and B2 slot to check if the system can boot into BIOSproperly.

4.     Reinstall CPU and check if CPUsocket pin is fine.

5.     If it is possible, pleasechange another CPU or DRAM to check if the system can boot into BIOS properly.

 

Thank you!

Yours truly,
