Computer errors can pop up when least expected, they can cause the entire system to suddenly shut down, and they can inadvertently corrupt data to the point where it can’t be deciphered. Although they can’t always be avoided, it’s important to remember that computer errors can be corrected. The key is to understand what computer errors are, understand what they mean when they show up, and understand how to minimize their occurrence in the first place.

Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They “operate” whenever there’s a conflict among commands. Remember that computers essentially run off of a series of commands and it’s usually a smooth process. But when one command conflicts with another command – or when one command asks for a process or information that isn’t available, the computer returns results that aren’t useable. That’s an error.

A budding e.g. of this kind of blunder is when users try to make use of module which isn’t germane for their system. Almost all modules accompanies a list of complement mandate which dictates what a mechanism needs to have in sequence for a module to work properly.

A plan government module which you’re meddlesome in might need a specific handling system, similar to Windows XP for example. And nonetheless this module might implement usually excellent upon a Windows 98 machine, it will beget a crowd of errors once a started.

Insufficient memory will cause errors as well. That’s why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc.) that it cannot find.

Because some programs share common files, errors can also occur when these shared files are not up to date. For instance, let’s say that Program A is already installed on a computer and it’s working just fine. Then let’s say that the user of that computer downloads and installs Program B. Program B uses a file that Program A installed much earlier, but when Program B is run, errors popup. Those errors are the result of Program B attempting to use an outdated (shared) file that was installed by Program A. In order to fix that problem, the user would have to download an updated version of the shared file (which to say the least – is not an easy thing to find or do).
