Optiplex 780 blinking green 3

I have a dell optiplex 780 that is all oem and clean. There is a blinking 3 on the front. I looked in the user manual and reseated the processor using new thermal paste and cleaning correctly. Self tested power supply passed. What is the next step before realizing processor is gone?
