basically you will need to buy another CPU that uses the LGA 775 socket type, and also check your motherboard manual to see what CPU's it supports. Or if you bought an HP or Dell, check Google or the forums to see what works with your PC. Before physically installing it, you should update the BIOS to make sure it will support the new CPU.
