A pentium 3 processor is probably in a Socket 370 socket.

None of the current processors would fit in this socket, so you would want to look at second-hand computer stores / markets or maybe in your local classifieds.

It might be worth checking what speed processors your motherboard can support up too before buying one.

To upgrade from a Pentium 3 to a Pentium 4 processor, you would have to replace the motherboard. The Pentium 4 processor has more pins on it than the Pentium 3 and would not sit in a Pentium 3 motherboard.

Upgrade the processor.

More important is the question of what processors can your motherboard handle. Certain motherboards accept certain sockets and speeds of processor, so you can choose from that to decide what you want to upgrade it with.

See page 8 of this manual. Your compuer has a Socket 370 processor, an Intel Pentium II. You can upgrade it with another one of those. Here's the manual listing the specs of the processor the motherboard can take:

Yikes, a Pentium II?? Unfortunately it will definately be more economical to just replace the whole motherboard, or the whole computer! This motherboard will only support a range of P2 processors, an upgrade will cost several hundred dollars, close to the price of a brand new computer with a P4 in it.

To upgrade from pentium 3 to P4 you have to change alot of the hardware.

You need a NEW P4 Socket mPGA 475 Motherboard.
New 478 PIN Processor.

You can use the old CD rom and Hard drive and any other PCI card but You Need the Mentioned Hardware to Upgarde.
