Why? A dirty optical-mechanical mouse (mouse with a ball) can cause the mouse to be difficult to move as well as cause strange mouse movement. Procedure: To clean the rollers of an optical-mechanical mouse you must first remove the bottom cover of the mouse. To do this examine the bottom of the mouse to see which direction the mouse cover should be rotated. As you can see in the below illustration the mouse cover must be moved counter clockwise. Place two fingers on the mouse cover and push the direction of the arrows. Once the cover has rotated about an inch rotate the mouse into its normal position covering the bottom of the mouse with one hand and the bottom should fall off including the mouse ball. If this does not occur attempt to shake the mouse gently. Once the bottom cover and the ball are removed you should be able to see three rollers located within the mouse. Use a cotton swab, your finger, and/or fingernail and move in a horizontal direction of the rollers. Usually ther

In the process of owning and operating a PC, you will, no doubt, find a point in time that the keyboard causes strange and irritating things to happen to your fond finger strokes. Nine times out of ten, this is caused by DIRT! It is amazing how much trash can be found under the keytops of any keyboard that has been in use for more than a few weeks. Human hands carry a great deal of trash, including dead skin cells. In addition, leaning over a keyboard, as computer people are prone to do, can cause much "head garbage" to fall into the mechanism. If you smoke (as I do), you'll find it next to impossible to keep ashes in the ashtray. The symptoms of a keyboard dirt problem are manifold, but the most common are: mistyped characters, missing letters (Did I miss the key?), and having the wrong character appear at the most obnoxious times.

Firefox has lot of memory leaks and that has been fixed the most in the latest release. Anyway that’s not our part Mozilla developers will take of that  If you think you can contribute better then join their team. Visit Mozilla today to find out more ways to contribute. Now let’s optimize Firefox to use less memory and to work faster. This is the smarter way too. Type about:config in the address bar. Create a new Boolean entry config.trim_on_minimize and set it to true (This one works gr8 when ever you reduce the FireFox window. It almost saves 20 MB – 30 MB+) Set browser.cache.memory.capacity to a fixed size (the default values are: for 256 MB RAM - 14336, 512 MB RAM - 22528, 1 GB RAM - 32768). This is free 22MB max. Set browser.sessionhistory.max_total_viewers to 0. It can reduce around 20 MB of usage Change image.animation_mode to none. It has little impact on performance. Now go to Tools/Options. Set the disk cache memory to a low value (less than 50 MB). Turn off Java (

The success of the Celerons created a great market for overclockers and for the most part it can be easy. There are several important factors that will determine success, of course the CPU itselfI chose the ABIT BE6 motherboard because it allows you to set the external clock speed, AGP clock, and voltage from the BIOS. This makes playing around with settings very convenient. The Celerons were excellent overclocking chips for two main reasons, an on-die L2 cache running at core speed, and a FSB speed of 66MHz. The on-die L2 cache was critical since this allowed many Celerons to reach bus speeds of 100MHz without failing. Many chips such as the PII or K6 don't have an on-die L2 cache and have less success handling the increases in bus speeds. Another critical factor was the Celeron's default bus speed of 66MHz. Since the Intel 440BX chipset supports bus speeds of 66 and 100MHz this gives the Celeron a lot of room to play. Another added value is that a 100MHz bus speed is suppor

With powerful processors and accesories, laptops now offer almost everything a desktop PC can offer Laptops can be divided into two weight categories :Ultralite and Regular. Ultralites are thin, small and weigh under 5 pounds but the drawback is their limited built-in features. Regular laptops, on the other hand, are bigger and heavier but they include such nice features as large bright screen; long-life battery; CD-ROM and floppy drive. Many portables also make room for optional DVD or Zip drives with USB and other interfaces for external devices Before buying a Laptop computer the following features will help you decide which is the right one for you: CPU: Although there are many factors that influence the performance of a computer, the most important one is its microprocessor, also known as its CPU (central processing unit). The microprocessor is a silicon chip (with millions of circuits) that is the brain of a computer. Its speed is measured in MHz (megahertz). Currently, speed
