HELP! Don't want to break something!

[mortonww]

It is extremely hard to push the processor socket lever down. I have the i7 lined up with the two notches, the top of the green circuit board is just about level with the socket. It IS socket 1366, this IS an i7, so that's not the problem. It's just almost impossible to push the lever down and I'm afraid that I'll break something. Can someone help me?!!

Also, my Ultra X3 1000 Watt power supply has a 24 pin connector. One of the gold pins on the "to motherboard" side of the plug is missing and isn't attached to a wire. On the "to power supply" side, however, there is a golden pin on the wire and the back of the power supply. Is this normal?
