Bad CPU?

I'm getting random reboots with 0x7f bugchecks. I've tested my ram, gotten a new power supply, etc. Everything checks out fine, so I'm down to either the CPU or the motherboard as culprits. How can I test CPU to see if it's good?

I've cooled down my Athlon XP 2600+ as much as humanly possible. I reseated it with good thermal compound and a brand new, all-copper heat sink. I'm running about 47 C at idle and about 10 degrees cooler on Prime 95. My computer still reboots when I run the "small fft" test. Does failure of this test specifically point to the CPU? My chip is still under warranty. Does this test reliably point to a bad CPU? If not, is there a way to test only the CPU to see if it is bad or not (perhaps another freeware program)? I need help. I'm at my wit's end.
 
The best way is to pull out the cpu and try it on anouther motherboard.Chances are it is the motherboard sience cpu problems are extremely uncommon. however a bad motherboard could have fried your cpu as well.The oposite is also true,a bad cpu can fry a motherboard so there is a decent chance they are both bad but you won't know untill you try.
