When you experience a shut down error, and your computer keeps shutting down randomly, there are a variety of possible causes for this type of problem. The best way to fix this shutdown error is to fix the problems which are causing your computer to shut down by itself. There is as a matter of fact a simple way to fix this problem once and for all. One possible factor which can cause the computers random shut down error is just that the machine is overheating. Modern high powered computers will produce considerable heat which is removed by fans in the interior of the machine. When the computer continues to overheat, even with the fans running, it can shut down by itself. This may be very annoying of course, but it prevents further overheating and damage to the machine.
Dust which accumulates inside the computer casing can be a reason for poor cooling. This problem can be tackled by opening the computer casing, and blowing the dust out of the computer with compressed air. You must of course unplug the computer before opening the casing. An ordinary room fan, positioned to blow air on the computer, can be a big help in keeping it cool also. If you find that a laptop overheats you could be accidentally blocking some of the fan vents under the machine while it is on your lap.
Another cause of a shutdown error, and the most likely one, is a problem which is unfortunately common in all Windows PCs. Windows can shut down your computer randomly if the computer registry becomes overloaded with data, and results in the operating system being unable to access files it requires to operate the system. The computer registry is a huge database which contains many files and settings that are required by the operating system. Any damage to the registry may result in Windows shutting down your computer randomly.
The computer registry is in fact a very common cause of problems such as a shut down error, slow running computer or freezing and crashing at random times. Registry problems are a likely reason for a computer to shut down by itself. The recommended method for fixing this problem is to find and download a registry cleaner on the internet. A registry repair tool will most often offer to give you a free registry scan, to determine whether or not there are problems in your registry. You then can decide whether you wish to have your registry edited and repaired by the registry repair tool.
