When you attempt to shut down your computer, start Windows, or start a program in Windows, you may encounter error messages that are similar to:
Fatal exception errors are codes that are returned by a program in the following cases:
A fatal exception XY has occurred at xxxx:xxxxxxxx
In the sample error message that is listed above, XY represents the actual processor exception from 00 to 0F. (Note that the "h" that is listed after the 0E, 0F, and so on, in the explanations below is frequently omitted from the error message.) The xxxx:xxxxxxxx value represents the enhanced instruction pointer to the code segment; the 32-bit address is the actual address where the exception occurred.
Windows does not cause these errors, but has the exception-handling routine for that particular processor exception, which displays the error message.

Processor Exceptions and Their Definitions
00: Divide FaultThe processor returns this exception when it encounters a divide fault. A divide fault occurs if division by zero is attempted or if the result of the operation does not fit in the destination operand.
02: NMI InterruptInterrupt 2 is reserved for the hardware Non-Maskable-Interrupt condition. No exceptions trap through interrupt 2.
04: Overflow TrapThe overflow trap occurs after an INTO instruction has executed and the 0F bit is set to 1.
05: Bounds Check FaultThe BOUND instruction compares the array index with an upper and lower bound. If the index is out of range, then the processor traps to interrupt 05.
06: Invalid Opcode FaultThis error is returned if any one of the following conditions exists:
07: Coprocessor Not Available FaultThis error occurs if the computer does not have a math coprocessor and the EM bit of register CR0 is set indicating that Numeric Data Processor emulation is being used. Each time a floating point operation is executed, an interrupt 07 occurs.
This error also occurs when a math coprocessor is used and a task switch is executed. Interrupt 07 tells the processor that the current state of the coprocessor needs to be saved so that it can be used by another task.
08: Double FaultProcessing an exception sometimes triggers a second exception. In the event that this occurs, the processor will issue a interrupt 08 for a double fault.
09: Coprocessor Segment OverrunThis error occurs when a floating point instruction causes a memory access that runs beyond the end of the segment. If the starting address of the floating point operand is outside the segment, then a General Protection Fault occurs (interrupt 0D).
10 (0Ah): Invalid Task State Segment FaultBecause the Task State Segment contains a number of descriptors, any number of conditions can cause exception 0A. Typically, the processor can gather enough information from the Task State Segment to issue another fault pointing to the actual problem. See Microsoft's Programming the 80386/80486 Guide for more information.
11 (0Bh): Not Present FaultThe Not present interrupt allows the operating system to implement virtual memory through the segmentation mechanism. When a segment is marked as "not present," the segment is swapped out to disk. The interrupt 0B fault is triggered when an application needs access to the segment.
12 (0Ch): Stack FaultA Stack Fault occurs with error code 0 if an instruction refers to memory beyond the limit of the stack segment. If the operating system supports expand-down segments, increasing the size of the stack should alleviate the problem. Loading the Stack Segment with invalid descriptors will result in a general protection fault.
13 (0Dh): General Protection FaultAny condition that is not covered by any of the other processor exceptions will result in a general protection fault. The exception indicates that this program has been corrupted in memory, usually resulting in immediate termination of the program.
14 (0Eh): Page FaultThe Page Fault interrupt allows the operating system to implement virtual memory on a demand-paged basis. An interrupt 14 usually is issued when an access to a page directory entry or page table with the present bit set to 0 (Not present) occurs. The operating system makes the page present (usually retrieves the page from virtual memory) and re-issues the faulting instruction, which then can access the segment. A page fault also occurs when a paging protection rule is violated (when the retrieve fails, or data retrieved is invalid, or the code that issued the fault broke the protection rule for the processor). In these cases the operating system takes over for the appropriate action.
16 (10h): Coprocessor Error FaultThis interrupt occurs when an unmasked floating-point exception has signaled a previous instruction. (Because the 80386 does not have access to the Floating Point unit, it checks the ERROR\ pin to test for this condition.) This is also triggered by a WAIT instruction if the Emulate Math Coprocessor bit at CR0 is set.
17 (11h): Alignment Check FaultThis interrupt is only used on the 80486 CPUs. An interrupt 17 is issued when code executing at ring privilege 3 attempts to access a word operand that is not on an even-address boundary, a double-word operand that is not divisible by four, or a long real or temp real whose address is not divisible by eight. Alignment checking is disabled when the CPU is first powered up and is only enabled in protected mode.
Troubleshooting Fatal Exception Errors
Clean Boot Your ComputerBecause there are many conditions that can cause a fatal exception error, the first step in resolving the issue is to narrow the focus. To narrow the focus, try a "clean boot" of your computer.
Clean-boot troubleshooting refers to methods of reducing problems that may occur because of your computer's environment. Many problems occur because of conflicting drivers, terminate-and-stay-resident programs (TSRs), and other settings that are loaded when your computer starts.
