Guide to help you give your system a boost by installing a AMd 64 bit processor into your Computer
Next, lift the small metal lever pictured, which will release your CPU. Remove the CPU holding the very edges and lay it on an anti-static surface.
Now you are ready to install your new CPU. Remove the chip from its plastic case and check which corner the marker is on. Line this up with the CPU slot on your motherboard and drop the chip in place. You should not need to apply any force at all, so if it fails to drop into place, check you have the pins lined up correctly and the marker on the CPU matches the marker on the slot. Also check that the metal lever is upright (which it may not be if you are installing the CPU in a new motherboard).
Next, push the metal lever down which will secure the CPU. Now you must install the heatsink and fan, which may have come bundled with the new CPU. Most new heatsinks contain a small block of thermal paste which will melt onto your CPU and form the necessary thermal connection as soon as you turn your PC on. If this is not present, you will need to apply a small drop of thermal grease or paste to the die of the CPU (The small chip in the centre of the CPU).
Next, place the heatsink over the CPU and secure it using the lever or clip. The lever arm must be pushed all the way down and clipped under the plastic, which will need significant pressure. The older style heatsinks clip to the board using a metal bar. 
This must be hooked over the plastic clip on one edge and forced down using a flat-blade screwdriver on the other. Once fastened, ensure that the heatsink is fitted securely, and plug the CPU fan into the appropriate power connector located on your motherboard.
If you removed your motherboard from the case, you will now need to put it back in. Secure the board with screws and replace any cables and expansion cards.
Finally, replace the sides of your case and boot your PC up. POST should show your new CPU, though you may be asked to enter the BIOS to confirm the speed of the new CPU. If you wish to double check, you can go to Start - Settings - Control Panel - System and check the reported CPU make and speed.
