A fatal system error is a computer operating system condition that causes it to stop functioning. It is caused by hardware failure, failed programming code, or processing errors in software running in memory. The most common cause is poorly coded software that is incompatible with the operating system. When a fatal system error occurs, everything the user was working on in RAM memory is lost. It is rare in modern computer systems, but can be caused by recently installed software or hardware. The kernel is the core of the operating system that interacts with hardware, software, and shells.
A fatal system error is a condition that occurs in a computer operating system that causes it to stop functioning. Both Windows® and Unix® based operating systems are designed to shut down on a catastrophic system error and restart in an attempt to clear the problem and any software corruption from memory. The problem has been given its colloquial name in Windows® as “the blue screen of death” because, when a fatal system error occurs in a Windows® environment, a blue screen, often with scrolling text, is displayed, which is a crash dump of memory contents to a file. This information can later be used to diagnose the cause of the failure. On the latest computer systems, the blue screen of death no longer appears, as they are immediately set to restart if the system crashes, mainly because the crash dump information is only useful to a programmer familiar with coding of the operating system yes.
Modern computer operating systems constantly go through an error-checking process as they operate and correct behind-the-scenes errors that personal computer (PC) users are rarely aware of. Occasionally, however, a condition arises due to hardware failure, failed programming code, or processing errors in software running in memory, that an operating system cannot fix automatically. The most common cause of a fatal system error is poorly coded software that is somehow incompatible with the operating system it is running on.
One of the more frustrating downsides of encountering a fatal system error, also known as a stop error or system crash, is that everything the user was currently working on on their PC and was being processed in random access memory (RAM ) will be lost. Since RAM memory loses data retention when the system crashes and shuts down, currently stored files cannot be recovered after a crash. If a computer or software program is designed to periodically save work in progress, such as a word processor set to save a document every ten minutes as it is being worked on, this data loss can often be avoided, since the file is saved to disk computer hard drive, not short-term RAM memory.
Computer errors that cause a system to crash were fairly common in the early days of personal computer system and software development in the 1980s and early 1990s, but have since become quite rare. When a fatal system error occurs on a new computer, the most likely cause is a recently installed new software program or a driver for a new hardware device that was recently connected to the computer. These types of crashes can be avoided by simply uninstalling the device or software.
Kernel failure or kernel panic are other initial computer programming terms for a fatal system failure. A kernel is the core of a computer operating system that interacts with hardware, software, and shells, which are parts of the operating system that respond to user input and commands. The operating system loads the kernel first at startup and remains loaded in memory as long as the system receives power, because the computer cannot function without it. Due to its essential nature, it is stored in a protected area of RAM memory which cannot be overwritten by other software while the computer is in use, and when a computer experiences a fatal system error, it means that this kernel of the operating system itself it was actually corrupted and didn’t work properly.
