for the full motherboard info. Most likely you are looking at a new mb, ram, cpu and gpu. What is your budget?

There is no AMD XP for socket 939, plus 939 came out less than 5 years ago so it wouldn't be in a 7 year old computer. Would of been nice for him if he did have one since you can upgrade to a dual core with one. But he most likely has a Socket A or maybe a 754 but those aren't even 7 years old.
In any case to the OP your basics of overclocking are to
find out what temps your system can handle (look online for your cpu),
go into the bios and raise the fsb up a little,
boot the computer up and test stability with a program like prime95 and monitor temps with a program like coretemp,
if its not stable but is running cool enough then add some voltage to the system (your need to figure out which things to raise by trial),
If you overclock the ram then run memtest86 to check that for stability(you need to make a bootable media like a floppy and boot into it)
repeat until you reach the highest safe speed you can then back down a little to ensure everything will be ok.
