If your computer keeps shutting down randomly there are several known possible causes for this behavior. In order to fix this problem you simply must fix the problems which cause your computer to shut down randomly, and there is a quite simple way to take care of this problem.
The most likely cause of the computers random shutdown problem is simply overheating of the machine. All computers produce quite a bit of heat which is taken care of by fans inside the casing. If the computer overheats despite the fans it may start shutting down randomly. Needless to say this is a huge annoyance, but it prevents damage to your valuable machine. One common cause is dust accumulating in the interior of the computer which can result in poor cooling. The solution to this is to open up the computer case and blow the dust out with a compressed air spray can. Unplug the computer of course before doing this. Playing air from a room fan on the computer will help to cool it also.
If your laptop is overheating it may be because you are blocking the fan vents, in the base, with the machine on your lap. The other and most likely cause is something which is common to all Windows computers. Windows will shut down the computer randomly if the registry is bloated with data, and the operating system cannot access the files it needs to run the computer. The registry is a massive database which holds all the files and settings needed by the operating system. If the registry becomes damaged or corrupt Windows may shut down your computer randomly.

You can then take a look at the results, and if you wish you can have the registry fixer edit and repair your registry. A good registry cleaner software tool, once downloaded and installed, will repair your registry quickly and efficiently and your windows system will run a lot more reliably once more.
