As long as the processors are have the same socket types (478) and the motherboard supports both processors then great.

When you say it doesn't recognise the CPU, do you mean in the bios or is there no POST screen?
What happens when you put the Celeron back in? Does it boot fine again?
Check the pins on the bottom of the P4 to make sure you didn't bend them when it was installed.
If you can boot with the celeron, go online and download the most recent version of the bios installed.

here is a list of supported CPU's for your board:

This is where you can download a bios update:

It could be that the processor is faulty but not likely.
