Did you make sure the marker on the CPU is lined up with the marker on the socket?
Are the retaining screws snug?
Did you reapply thermal paste?
Did you run the setup disc?
It is and when using the lock screw (The slot headed one one on the socket) is clicked into place.
Very much so and I used new silicon paste.
I don't have one. so that would be a no. how ever there is no way I could run a disc as the system is not starting to anything that could open and start said disc.
