so i just received my b350m gaming pro from a friend that sold it to me due to him not being able to use it cause he bought a ryzen 5 chip and needed a bios update to fix it, i put only my ryzen 7 1700 in along with the cpu fan i turned it on and the cpu and ram light came on i know why the ram debug led came on but i have no clue why the cpu one did if the b350m gaming mobos should support ryzen 7 out of the box
 
Solution
The debug LED turning on for few seconds does not indicate a problem. A problem is indicated only if the debug LED stays on and the computer will not boot.
