Machine_check_exception Error

Well, I am having my first major problem with my PC in 7 years. Recently, I started getting the dreaded Blue Screen errors. This problem occurs randomly. I thought at first that I may have a corrupt systemf file, so I reformatted my HD and started from scratch. Still the same outcome.

MACHINE_CHECK_EXCEPTION

Stop: 0x0000009c (0x00000000,0x8054D570,0xB2000000,0x1040080F)


I have read several of the threads here concerning this problem and I am unsure of where I need to start. I haven't made any changes to my hardware recently. I have checked all of my cooling fans and they appear to be working fine, I even installed an additional cooling fan to be sure that it wasn't a thermal issue.
I have tried removing my RAM and switching it between banks. I have ran the CPU with both sticks and with individual sticks. Any help that you could give me would be greatly appreciated.

SYSTEM INFO:

Pentium 4 1.7 GHz
768 RAM (DDR266)
Windows XP

Anything else that I can get you to help solve my prob,let me know and I will be more than happyto get it.
