Phil....
On the Biostar Z170 motherboard, what does the code "3C" and "AO" on the LEDs mean?
Is there a table for the code values and description?
I tried googling it and also Biostar website but no luck.
The rigs are working fine though, but out of the 5 x Z170s, 2 are with "3C" and the rest "AO" codes on the LEDs.
Thanks
A0 means good boot. If I don't get an A0 I get no screen just black.
Give me a minute I think I know the 3c code

I found the A0 but not the 3Chttp://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=807#download10
