Hello, @edddlewa_ and thank you for reaching out.

However, here is a forum for discussing Zenbook problems.
If you want to inquire about motherboard-related products, you are most welcome to visit our ROG forum for further discussion. Our moderator will assist you in investigating this matter.

Meanwhile, regarding your description, if you have been unable to boot, I suggest you refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display for troubleshooting and try clearing the CMOS first.
If you are able to boot but cannot enter the OS, please refer to [Motherboard/Desktop] How to restore BIOS setting? to restore the BIOS settings.

Thank you.
