Causes why computer fails

Take the power cord out the back of your computer and open the case. Try taking out the memory modules and the putting them back with a bit of a shove. This is called reseating. Sometimes you have to repeat the process a few times. The bad electrical contact occurs as a result of a gap opening up, or a bit of corrosion or dust getting between the electrical contacts.

Reseating works in very many cases. This is much the same problem as with the memory modules, except the video card need to be reseated. Of course, your computer may not have a separate video card.

The two most probable causes of this are:. If it is a matter of missing files or files that do not read, then running software such as Spinrite can make a difference.
