This type of error is commonly associated with the blue screen of death in Windows, but less severe fatal exception errors only cause a single program to close. In some cases, fatal errors are spontaneous and temporary, and you can safely continue using the computer without any additional problems.

If fatal errors persist, and especially if these errors reoccur when using the same program or performing the same task, there could be a problem with either the hardware or software on the computer.
How Fatal Errors Appear
Fatal error messages typically appear when a program suddenly shuts down because of some type of failure, or when a Windows computer suddenly displays the blue screen of death before shutting down, or when a macOS or Linux computer suffers a kernel panic.

The specific type of error, and the series of numbers and letters that are often included, can help track down the problem.
What Causes a Fatal Error
When you run a program on an operating system like Windows, and the program encounters something unexpected, it generates a message called an exception.

These exceptions allow programs to run smoothly and operate normally, even when something unexpected happens. When a program is given or generates an unknown or unexpected exception, the result is a fatal error.

Some fatal errors are fairly basic, but most error messages provide a code that can help you find specific information about the problem. If the error looks like this: A fatal exception 0E has occurred at xxxx:xxxxxxxx The 0E is a code that might point you in the right direction. Run a search for the specific fatal exception error code, and see if you can find specific instructions.

The other code, which usually follows the format of two sets of numbers separated by a colon, may also help. This code is less likely to yield results, but it's worth a quick search before you move on. Update the software.

The developers may have released a patch designed to fix the specific problem. Most programs and apps either download and install updates automatically, provide you with an option to manually download and install updates, or prompt you to visit the developer's website and download the update. If you can't figure out how to update the software, check out our list of free software updater programs.

These programs keep all your programs up to date. Update the drivers. Unexpected interactions involving drivers can cause fatal errors, and other problems, so it's always a good idea to keep the drivers up to date.

If the drivers are up to date, roll back the drivers to earlier versions. There's a chance the old drivers were fine, but an automatic update introduced the fatal error. Check to see if any drivers were updated immediately before the problems started, and roll those back first.

If you saved system restore points from before the fatal errors appeared, restore Windows to one of those points. This step rolls back any changes made during that time span, which will fix the fatal error problem if it isn't related to a hardware glitch.

You can safely shut down any program you originally opened, but closing unfamiliar or system-level apps and background processes may destabilize the operating system, necessitating a reboot. Delete temporary files. Temporary files save when programs are running, but sometimes these files aren't deleted when the program closes.

If the fatal errors are caused by a problem with the hard drive, then running chkdsk can identify the error and either fix it or at least let you know what's going on. Rule out heat problems. If your computer overheats, it generates several fatal errors in addition to a variety of other symptoms.

Verify that the fans work and aren't clogged with dust or debris. If you're comfortable taking the computer apart, check the internal fans and the heat sink. Carefully use canned air or a vacuum to remove any dust or debris that prevent the fans or heat sink from functioning efficiently.
