I'd be willing to bet that the CPU itself is still good, unless the heat sink assembly failed first and the MB didn't have any failsafe for processor overheat. The age of the capacitors on the MB is such that the most likely culprit is the mainboard, since those do degrade over time, although the ones inside the power supply fail at a much higher rate.
Here's a "Buy it Now" option for $24 for a Biostar MB to fit your CPU, although it will probably want to set the multiplier to some lesser processor's speed instead of the XP 2700's actual multiplier. It comes with a T-Bird 1.0 GHz processor, but those ran way too hot for the stock heat sink assembly.

Biostar was producing and selling mainboards for the AMD Athlon XP processors long after anyone else had stopped doing so. There is one particularly good reason fo stuffing an old XP machine under the computing table, and that is the KotOR game, which doesn't run well with recent OSes or GPUs.
I've always liked Gigabyte's mainboards, though, and this next one would know what an XP 2700 was all about, for $39, with shipping, or you can make a "best offer" on it:
