Pentium 4 lasted for a long run and actually spanned across a few different changes in technology, some of those changes are cpu dependent and some are motherboard dependent.
Download cpuid and tell us what pentium 4 (need a specific model number like a 631, etc) and what motherboard. Without that we would be only guessing.
I would not sink any money into that computer though, you can buy off lease desktops from newegg/tiger direct for $100-150 that are far better then that old p4 machine. They are not gaming machines by any means but still dual core cpus that are much newer then an old p4.

I actually have such a mobo, the intel 945GC. It supports newer P4's and core 2 duos upto the e4700, but the e4xxx core 2 duos are not very powerful.
If you're tight on budget, get a pentium G series or a core i3, but don't get core 2 duos now.
