We're going to assume you have an Intel motherboard and processor to hand, both still in their boxes.

Step 1: Remove the motherboard from its box and protective packaging. Place the anti-static bag and foam mat under the motherboard to protect it, then lay the board down on a flat space like a table.

Gently but firmly press the metal lever down and away from the Socket to release it, then pull it back until it hangs loosely. This will release the shim (load plate).

Using the small metal tab on the right edge of the load plate, push down to flip up both the plastic cover and the load plate to expose the socket and pins. Make sure not to touch the pins! Take a moment to examine the pins, ensuring that none are bent and that no foreign material is present.

If you see anything out of position, a pin may be dislodged from the LGA775 socket. In this example below, one pin is slightly out of place.

Rather than returning the board for replacement, it was possible to very carefully nudge it back into place with the tip of a sharp pin. Now back to the installation...
