Stop Error C2

Hi guys. I am getting a stop error C2 on a Toshiba Satelitte M30-S309 running Windows XP Pro SP2 with all the updates as of last week.

BAD_POOL_CALLER
0x000000C2 (0x00000043, 0xD232A000, 0x0000000 0x00000000)

I get this error on bootup no matter if I am in Normal, Safe Mode, or any of the other safe modes. I can however (obviously) boot into a PE enviroment. Below is my log for WinDBG using the minidump of my last crash.

Please let me know what I can do, try, or what other information I need to include.

Thanks
