Bug Check 0x133 DPC_WATCHDOG_VIOLATION
Really not sure what to do with this one; never seen anyone actually report it before...
For now, I would treat this simmilar to CLOCK_WATCHDOG_TIMEOUT (0x101) and assume either an underpowered or overheating component. Make sure nothing is overheating, and if you have any OC, remove it.
Failing that, try running memtest86+ for a bit to see if you have any RAM errors.
