Dear Murdock9,
Greetings, this is ASRock TSD.
According to debug code b7, it may be related to memory.
Please re-install the CPU and memory then clear CMOS.
If the problem still exists, please install only one memory module or using other memory modules.
Besides, please follow below steps to update BIOS from the fail ROM for verifying:
1. Please enter to BIOS setup > Tool page > Secure Backup UEFI to backup the ROM data into the fail to boot up ROM.
2. Use Instant Flash to update BIOS to the latest P7.20 version to try:
Here's the SOP of Instant Flash:
3. After finishing above steps, it may possibly able to boot up the system with BIOS P7.20
By the way, if your system is stable in previous BIOS P3.20 version, we would suggest maintaining the status.
Thanks!
All the best,
ASRock TSD
