A fatal error is a type of error that forces a computer program khổng lồ cthua or the entire operating system lớn shut down suddenly. This type of error is commonly associated with the xanh screen of death in Windows, but less severe fatal exception errors only cause a single program lớn cthua trận.


In some cases, fatal errors are spontaneous and temporary, & you can safely continue using the computer without any additional problems. If fatal errors persist, và 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.

When you experience a fatal error message, whether or not it looks exactly lượt thích these examples, write down what you see. The specific type of error, & the series of numbers và 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 lượt thích Windows, & the program encounters something unexpected, it generates a message called an exception. These exceptions allow programs to lớn 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. This same type of problem can also be referred khổng lồ as a fatal exception, or a fatal exception error.


Depending on the severity of the error, you may be given the option to lớn continue running the program, or the program may terminate automatically.


How khổng lồ Fix a Fatal Error

Fatal errors can be caused by a variety of unexpected interactions between different programs, between programs và drivers, between programs & the hardware, and physical faults or defects in the hardware.


Search for the error code lớn find specific instructions. 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 lượt thích 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 tìm kiếm for the specific fatal exception error code, & 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 quichồng tìm kiếm before you move on.


Update the software. The developers may have released a patch designed to lớn fix the specific problem. Most programs và apps either tải về và install updates automatically, provide you with an option khổng lồ manually download & install updates, or prompt you khổng lồ visit the developer"s trang web and tải về the update.

Update the drivers. Unexpected interactions involving drivers can cause fatal errors, và other problems, so it"s always a good idea to keep the drivers up khổng lồ date.


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


Uninstall any recently installed programs. There may be an unforeseen conflict between the programs, or something could have sầu been corrupted during the installation process. After uninstalling the recently installed programs, check lớn see if the fatal exception error still happens. If it doesn"t, reinstall the programs. If the problem comes bachồng, submit a bug report to the developer.


Restore Windows lớn an earlier state. If you saved system restore points from before the fatal errors appeared, restore Windows to lớn one of those points. This step rolls baông chồng any changes made during that time span, which will fix the fatal error problem if it isn"t related lớn a hardware glitch.


Disable unnecessary background programs. You don"t see these programs on the taskbar, but you can open the task manager to lớn shut them down manually. In most cases, background programs can be left alone. However, there are cases where one of these programs may conflict with a different program in an unexpected way, causing a fatal error.


Don"t shut down programs you"re unfamiliar with. You can safely shut down any program you originally opened, but closing unfamiliar or system-cấp độ apps và 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 corrupt temporary files are the cause of the fatal exception errors, then removing these files will fix the problem.


Free up space on the hard drive. Chechồng how much space is on the hard drive sầu, & delete old files if the drive sầu is full. Leave about 10% of the total storage space không lấy phí for smooth operation.


Run chkdsk. If the fatal errors are caused by a problem with the hard drive sầu, 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 lớn a variety of other symptoms.

Verify that the fans work và aren"t clogged with dust or debris. If you"re comfortable taking the computer apart, kiểm tra the internal fans and the heat sink. Carefully use canned air or a vacuum to lớn remove sầu any dust or debris that prsự kiện the fans or heat sink from functioning efficiently.


If you use canned air, hold the can upright khổng lồ avoid spraying liquid inside the computer. Don"t touch the components inside the computer if you aren"t wearing a properly phối up ground strap. If you aren"t comfortable poking around inside a computer or máy tính xách tay, seek professional assistance.


Test the random access memory for problems. Memory errors generate fatal errors, although you may see a memory exception or an out of memory exception error instead. Run a memory demo application. If you discover that the RAM is faulty, replace the defective sầu component or components.


Cheông xã the rest of the hardware. If you experience recurring fatal errors, & everything has checked out so far, you might have a subtle problem with some of the hardware in the computer. In some cases, replacing components like the hard drive sầu or motherboard can fix fatal errors.
