Hi Daniel, sounds like you may have the cpu placed in the wrong way. there is only one way it will go in so maybe if you take it out and check the cpu or motherboard manual. I know gigabiyte and p4 has two notches that have to be aligned. Hope this helps Steve ----- Original Message ----- From: <[log in to unmask]> To: <[log in to unmask]> Sent: Friday, July 21, 2006 12:57 AM Subject: [PCBUILD] Heatsink/Fan Installation Problem This is my first build and have just encountered a problem. I just installed the Heatsink/Fan. AMD AM2 with retail heatsink. I snapped both clips in place. The AMD video says that I should pull the black lever down and snap it into place. It wont budge. I think that if I put any more force on it, it will break. Any insight would be greatly appreciated.
