processor installation hasnt really changed. any processor chip works in the same way. (none of hte slot processors installation will apply now, if u watched a video where the cpu is encased in the black rectangular block and isnt a chip with a pin grid thats not gonna help you). installing processor is EZ. lift up the little plastic or metal arm on the slot on the motherboard until it is stadning strait up (or simply as high as it will go). Line up the triangles on the socket and chip and hte processor will literally fall into place. NO force is necessary. once processor in all the way push the lever back down and the processor will be locked into place. Installation of Heatsink hasnt Really changed either. make sure there is thermal pad/paste on the bottom of the thing, line up the clamp and clamp the cpu heatsink to hte cpu. Make sure you plug the cpu fan into the motherboard. For the Socket 462, 370, it is hook it on 1 side and push down and hoook the other side with a screw driver. for Socket 754, 939, 478 (probably 775 idk never worked with them before) its screw driverless. place heatsink on top of cpu and lock the 2 sides of hte thing. no problems. It may seem intimidating at first but once you start doing it you will realize its mostly common sense and a piece of cake (heck it might take you longer to eat a piece of cake than installing a processor). As for over heating, most motherboards have a temp monitor somewhere in the bios just look and if ur processor is registered to be between 30-50 degress centigrade you should be fine (50 is a tad high but bearable).
any questions?
