A little preplanning is the key. Research what MB's are compatible with your current processor. Make sure that the processor is assigned to the same slot. You can find this information on most any MB suppliers web site. Be especially careful when removing and instaling processor. Make sure that all power is disconnected and also make sure not to bend the pins. Also make sure to use a good heat sink compound when reinstalling the processor. Good luck.
