Check for bent pins.
I was upgrading my computer the other day by putting in a new CPU. I was exchanging an i3 for an i5. So I remove the fan, remove the old i3 and put in the new i5. But then I get the beep code I attached, I try to put in the old processor and get the same beep code. I take out all components except the processor with only the motherboard being powered, same issue. I take out processor and run it, no issues. Does anyone know anything I should try? and yes before you ask they are compatible.
