Computer slow down can be due to several reasons. It can happen suddenly or the computer becomes slow gradually. A sudden computer slow down is usually due to the presence of some spyware or adware. In such cases, an adware/spyware remover can be used to restore the speed of the system.

Many times, computer becomes slow progressively and it is not able to make out the changes unless it becomes extremely slow. The system may take a very long time to start and shut down. It will take more time to start many applications and programs. Computer users find these problems irritating and hampering their work.

The chief reason for the slow pc, which was working normally at the time of purchase, is the presence of registry errors. Registry is an important part of the computer where a lot of information will be saved. The more one uses the computer, the more data will be present in the system registry. As one uses and uninstalls different programs, there will be bloating of the computer registry with redundant data.

Cleaning of the registry and its repair is the first and foremost solution for the slowdown of computers. It requires a lot of expertise to tackle the registry problems manually. This is mainly because any unnecessary removal of the data from the registry can damage the system. A good registry cleaner will clear the registry of all unwanted data and restores the speed of the system.

Many registry cleaners are available in the market. Hence it is difficult to choose a particular registry repair software. Check for the features and reviews of such products to make a decision. Many of them offer a free scan of your computer to assess the status of the system. Backup and restore are the essential requirements of a good registry cleaner.

Apart from the registry errors, other problems associated with the hardware and disk can also contribute to the slowness of the computer. A poor RAM requires it to be upgraded to improve system performance. Cleaning the hard disks, disk fragmentation etc are also remedial measures for the slowing down of computer.

A corrupted registry can do more harm than the slowness of the system. Registry errors can cause system crashes, freezing of the computer, frequent error messages and other perturbing problems to the users. Hence it is recommended to do a registry scan periodically to keep the computer free from problems.
