I'm stumped. I just put this together and the three LED's on the edge of the m/b are flashing red as soon as the PSU is plugged in. I can't find any documentation about what that might mean. Strange thing is the system BIOS comes up just fine, recognizes the empty M.2 and HDD.

Googling got me nowhere. Any ideas? Thx.

Dear Mahjongguy,

Thank you for choosing ASRock.

Regarding your question, the flashing red LEDs are the onboard RGB LEDs.
The LEDs can be control by ASRock Polychrome RGB utility.
