Thus the motherboard serves as the ‘mediator’, a channel that allows the components to work together and walk to each other, making it a whole and completely working unit.

3. RAM – short for Random Access Memory. It is the memory used to process applications. RAM is lost when the computer is turned off.

4. ROM – short for Read Only Memory. It serves as memory for storage of programs.

5. Storage Devices – External storage devices like CDs, DVDs, USB flash drives are important as removable storage devices that you can take from one personal computer to another.

6. Power Supply Unit (PSU) – this converts the AC power to low voltage DC power, integral for the internal components of the PC.

Most people are not informed about the necessity to have a computer registry cleaner. The primary reason for having a registry cleaner is to increase the speed of the computer’s performance. While you install several programs and make use of your computer hardware, there is a greater tendency that your registry has unwarranted entries in the registry.

To ensure that your computer is running smoothly and speedily, it would be an imperative to avail a registry cleaner rather than manually doing the cleanup of the registry. With a software, you can clean your registry and keep them free from errors by just simply clicking the mouse. Aside from a registry cleaner, it is also important that your computer has an antivirus software in it. The combination of a registry cleaner and an antivirus software will definitely safeguard your computer from various threats and keep it running in an improved speed.

What is the usual cause of a system slowdown? Every time you install a program or hardware to your computer, additional entries are made in your computer registry. You might assume that uninstalling a program might avoid having additional entries to the registry. However, this is not the case because removing a program does not necessarily remove such entries in the registry.

In the end, adding and removing programs reduce the speed of the system’s operation. Furthermore, there is a probability that unnecessary entries in the computer registry are infected with adwares and malwares that bring about computer problems such as pop up’s and alteration of the page. With these taken into account, it is important to have a registry cleaner installed in your computer to maintain smooth operation of your computer.

To speed up your hardware, you may consider buying supplementary hardware. However, installing a new hardware could be quite expensive. For practicality’s sake, you can consider some other cheaper alternative ways to speed up your system.

On a regular basis, run a Disk Defragmenter. With regular defragmenting, the period of time needed for searching and merging fragmented files in the hard disk could be sped up.

If errors are present in the disks, such errors must be identified and fixed at once. This fixing of errors can be taken care of by an effective registry cleaner. Such errors in the hard disk slow down the system and may not allow writing of data in the hard disk. To avoid these problems, you can make use of the Error Checking Utility, a feature in Windows that identifies errors as well as bad sectors in the hard disk and fixes such errors immediately.

Rendering the indexing services of your computer also enhances the speed of the system. You can also disable other operations such as the settings that you do not regularly use. You can also do away with the speed fonts that you do not normally use. These measures allow less activity to your system, making it run more smoothly.

The best measure to speed up the system performance is to install added RAM memory. Greater RAM memory efficiently assists in operating most programs and retrieving information more quickly. Also, if you conduct a Boot Defragment, you can reduce the startup time. Installation of antivirus and antispyware software is also a great help in protecting your computer from threats of viruses.

If you want your system to function at its best condition, then you must regularly eliminate disk errors, take out temporary files, and organize your data.
