i found this on a site hope it helps!
Are you seeing this, "This program has performed an illegal operation and will be shut down"? This is known as a GPF or General Protection Fault. Some people call it a General Protection Error, not to be confused with a General Page Fault.
A General Page Fault - Invalid Page Fault, is different from a General Protection Fault. A Page Fault is caused by low or damaged physical memory, low free space for the paging file (swap file) or by a program accessing data in memory that is currently being modified by another program. It is called a Page Fault because the error is in the Paging of memory.
Program Error Messages (The big red X and a message stating that such and such program performed an illegal operation and will be shut down) are Invalid Page Faults, but the OS had a built in error trap to catch the error before handing it off to the CPU. To find andf fix these errors use System Sentry, now let me explain.
General Protection Faults are often caused by a software problem, you may need to update a device driver. It can also be cause by a program loading a DLL into memory at an address that is already used.
GPFs come from the CPU when it has exceptions and interrupts. When the CPU has exceptions and interrupts the CPU executes switches to a completely different code path to handle some external condition in the executing code. An interrupt is typically caused by an external stimulus—for example, a keystroke being hit. An exception is caused by an internal condition in the code or data that causes the processor to generate an exception. A classic example of an exception is the CPU attempting to read from a memory address that doesn’t have physical RAM mapped to it. Which means there is no such memory address
