Cause
Fatal exception error messages are generated when one of the below situations occur.
- Access to an illegal software instruction has occurred.
- Invalid data or code has been accessed.
- The privilege level of an operation is invalid.
Any of the above issues could be caused by one or more of the below possibilities.
- Errors in programming code, either a program, operating system or hardware driver.
- Conflicts between two or more programs.
- Physical hardware issue.
- Computer overheating
Solution
Microsoft Windows and software use exceptions, which allow Windows or other software to communicate in layers and communicate errors or exceptions. If a program is given an exception that is invalid or unknown you'll encounter a fatal exception. Fatal exceptions are also commonly referred to as a Fatal 0E (or improperly as Fatal OE) and is one of the most common fatal exceptions.When a fatal exception is encountered the error will be in the below format.
A fatal exception <YZ> has occurred at xxxx:xxxxxxxx
In the above example of the fatal exception the YZ represents the actual processor exception, this can range from 00 to 0F. Each of theses processor exceptions are explained under Extended information.After the processor exception is the enhanced instruction pointer to the code segment and the 32-bit address. This is exactly where the error exception has occurred.
Search for the error
Often the easiest and fastest method to locate the cause of a fatal exception is to search for the error. However, for some users it may be difficult to know exactly what to search for because of the cryptic fatal exception messages. Below are tips on how to search for these errors.
- As mentioned above the fatal exception will often have a two character code, for example 0E, if this code is present use this as part of your search.
- Next, the error message will contain a pointer such as "0028:c001e36", although this can often be found by also adding this to your search query it's important to realize that this pointer can vary from computer to computer. If you're not finding results exclude this from your search.
- Finally, many fatal exception error messages will also contain a file that generated the error, almost always this is a VXD file. If the fatal exception error contains a .VXD definitely include this as part of your search. The VXD file may also be listed as "VXD VWIN32", which is "vwin32.vxd".
If searching for the fatal exception error does not return results or help resolve your continue reading through this document for general recommendations in resolving fatal exception error messages.
Revert Windows back to an earlier copy
If this has just started occurring and you're running Windows XP or later restore Windows back to an earlier copy.
Update software or check for software patches
If you are experiencing invalid page faults in only one program, verify that the software program is compatible with the operating system you are running the program within. Also verify with the manufacturer or vendor of the software program that there are no available patches or updates for the program that may help or resolve your issue.
It is also important that you have all the latest Windows updates.
Hardware drivers
If you are getting a fatal exception when using a hardware device, for example, when you print. It's likely that it's the drivers related to that device that are either conflicting or have errors.
Video drivers are also notorious for causing fatal exception error messages. Because your video card is being used all the time it's difficult to know for certain if it's the cause of the error. Therefore we always recommend users have the latest video drivers on their computer.
Visit the manufacturers web page and get the latest software / drivers from them. See the computer drivers page for a listing of hardware companies.
Recently installed software / hardware
If you have recently installed new software or hardware uninstall or reinstall that software / hardware to verify it is not causing your issue. In the case of a hardware device it's suggested instead of installing the software or drivers that came with the device that you visit the manufacturers web page and get the latest software / drivers from them. See the computer drivers page for a listing of hardware companies.
Remove all TSRs
Disable any TSRs or programs running in the background as many times fatal exception errors can be caused by conflicts between two or more open programs.
Delete all program temporary files
Delete all temporary files that may still be residing on the hard disk drive from currently or previously running programs.
Overclocked computer
If you have overclocked any component within the computer, set the computer to its factory settings to verify that the overclocked component is not causing the issue.
Verify your computer has more than 200 MB available
If your computer is running low on hard disk space, your Windows swap file will be unable to increase in size when needed, which can cause errors.
Run ScanDisk and Defrag
Run Scandisk and run Defrag on the hard disk drive as it could be possible your hard disk drive may have an issue causing the swap file or data files to become corrupt or invalid.
Heat related issue
Verify that all fans in and on your computer are properly working. If not all fans are working or you do not have enough fans and your computer is overheating, any number of issues including fatal exceptions can occur.
Disable External Cache in CMOS
If the option is available, enter your computer's CMOS setup and disable the external cache. If this resolves your issue it is likely that you are encountering a heat related issue.
CPU Core Voltage
If available, verify within your CMOS Setup or by jumper that your CPU core voltage is set to factory specification. This may require that you consult your documentation or motherboard manufacturer.
Bad Memory, invalid bits or physically bad memory
Bad computer memory is also a common cause for fatal exception errors. If you have recently added memory to the computer, it is recommended that it first be removed to verify that you are not experiencing conflicts with the recently installed memory.
If no memory has been recently added to the computer and you have tried all the above recommendations test your computer memory for errors.
