bad pool caller - please help! Dell Inspiron B120?

how can i get past the BAD_POOL_CALLER error?

i had windows XP on my dell desktop, but was going to reinstall it. i put in the OS cd and started it. half way through it came up with the message about BAD_POOL_CALLER. i restarted several time, trying safe mode(which it won let me do in the middle of setup) and unplugging everything but my monitor and keyboard. i have no usb devices but my printer which was unhooked. i dont know what else to do!

I am having the same problem as theresa
Please help me, too!
