WTF is a chip puller? I've never heard of one before.
Bizarre69, changing a CPU is easy, once all of your homework is done. Using Intel for an example, you're not going to be able to upgrade from a P2 chip to a P4 chip on the same mobo, but will probably be able to upgrade from a slow P4 to a faster P4 (depends on mobo limitations). Like Deadguy said, we need to know make and model of mobo to be able to help.
