Tips To Make Your PC Run Faster

Remove Malicious Programs

It is important that you use up-to-date security software to detect and remove malicious programs. Virus programs can slow down your PC and cause unwanted behaviour, even damage to your data.

Spyware tracks your movements on the Web for advertising purposes, but can affect your PC's performance as well. Use anti-spyware programs to remove it.


Clear Out Junk Files

Any time you visit a web site, your computer needs to download the page along with any pictures displayed on it. To prevent your computer having to download the same files again each time you visit the same web site, your web browser will keep a "cache" of stored files it will retrieve if the site hasn't changed since your last visit. Although this means web pages appear faster, over time your cache can eat up a lot of disk space and slow your PC down.

Whenever you delete a file, it is moved to the Recycle Bin first, to give you the chance to change your mind. But the Recycle Bin uses disk space too, so if you leave lots of files in there you are wasting precious space.

Windows 7

Microsoft can do better than Windows Vista.

And with Windows 7—expected sometime before the year is up.

Whether it's the new features or the less taxing system requirements, Windows 7 promises to be a vast improvement on Vista, and hopefully enough to coax most of us still clutching XP for dear life to finally upgrade.

Monitor the temperature of CPU

Core Temp is a software that helps you keep checking the temperature of CPU.

The unique point of Core Temp is that it can have separate monitor to check the temperature of separate CPU. As such, if you are using Duo Core CPU, you will then be provided with two meters of temperature.

It can also enable you to know the real-time changes of temperature too. Of course, graphical representation to users is also available.

What is an Operating System

The operating system is the core software component of your computer. It performs many functions and is, in very basic terms, an interface between your computer and the outside world. In the section about hardware, a computer is described as consisting of several component parts including your monitor, keyboard, mouse, and other parts. The operating system provides an interface to these parts using what is referred to as "drivers". This is why sometimes when you install a new printer or other piece of hardware, your system will ask you to install more software called a driver.


What does a driver do?.

A driver is a specially written program which understands the operation of the device it interfaces to, such as a printer, video card, sound card or CD ROM drive. It translates commands from the operating system or user into commands understood by the the component computer part it interfaces with. It also translates responses from the component computer part back to responses that can be understood by the operating system, application program, or user. The below diagram gives a graphical depiction of the interfaces between the operating system and the computer component..

Causes of a slow PC

There are many possible causes of a slow PC. Because your computer is constantly working with files - moving, copying and deleting from place to place - it will eventually get cluttered with leftover files, some of which are not needed and just take up valuable disk space. You only have a certain amount of disk space available on your hard disk, and as it fills up the computer can begin to struggle to find room to perform its tasks.

If your PC crashes or freezes up, it may be a symptom of a slow or cluttered PC.

The brain of your computer is the Processor, and it may be that your processor is too slow to run today's demanding software. The processor can also struggle if you have multiple programs running at once - for example, if you have Word open to compose a letter while downloading a file from the Internet and also operating another application through your media player.

RAM is the temporary memory the computer uses to do its calculations. If you do not have enough RAM, your programs will run slowly.

Other components of your PC can contribute to poor performance, particularly your Graphics Card when it comes to running media and games software. Some hardware needs special programs called Drivers and these need to be kept up to date.

You may also have programs running in the background using up memory that you are unaware of, and in some cases, the problem may be a malicious program such as a virus or spyware.

How To Use Your PC Mouse

The Mouse is the device you will use for most of your interactions with your PC. It is primarily used to move the pointer arrow around the screen and to select and activate options.

The mouse buttons are used to interact with whatever is on the screen where the pointer is located. The left mouse button is the one you will use most often. Clicking this tells the PC to select an item and is called 'left-clicking'. To activate an item and use it, you will often need to click the button twice or 'double-click'.

If you click and hold the left button and move the mouse, this has the effect of 'dragging' a selected object about the screen until you release the button.

Left-clicking on text in a document will place a flashing cursor at that point, which allows you to begin typing there.

The right mouse button is usually used to bring up a small menu window that gives options specific to the selected object. To use a particular option you just left-click it.Common right-click menu options for an object include: Open (activate, same as if you double-click), Cut (remove to be placed elsewhere), Copy (make a copy of this object) , Create Shortcut (create a shortcut link elsewhere to give quick access to this object), Delete (remove permanently), Rename (give a new name), and Properties (find out information).

You may have a third smaller button in the center of your mouse that can be rolled forwards and backwards. This mouse-wheel can be used to move up and down through documents.

Windows OS

The operating system (OS) that runs all your programs and allows you to easily interact with your PC is called Windows for a good reason.

It allows you to work with several different items and programs at once, all in their own 'window'. A window is like a smaller screen contained within a box on your main screen.

When you are working with a window it is brought to the 'front' of the screen, overlapping the Desktop and any other items behind it, so that you can focus on whatever is in the window.

In this way, you can have several windows open at the same time containing different programs that can be opened, closed, and re-arranged across the screen. This means you can do multiple tasks at the same time, such as listening to an audio program while writing an e-mail for example.

How do optical mice work?

It appears that the venerable wheeled mouse is in danger of extinction. The now-preferred device for pointing and clicking is the optical mouse.

Developed by Agilent Technologies and introduced to the world in late 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complimentary metal-oxide semiconductor (CMOS) sensor. The CMOS sensor sends each image to a digital signal processor (DSP) for analysis. The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. Based on the change in patterns over a sequence of images, the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. The computer moves the cursor on the screen based on the coordinates received from the mouse. This happens hundreds of times each second, making the cursor appear to move very smoothly.

Optical mice have several benefits over wheeled mice:

· No moving parts means less wear and a lower chance of failure.
· There's no way for dirt to get inside the mouse and interfere with the tracking sensors.
· Increased tracking resolution means smoother response.
· They don't require a special surface, such as a mouse pad.
