Firstly unplug your mouse from the PC and get to hand a soft tissue and suitable cleaning fluid (window cleaner is fine).
Notice the removable cover on the bottom of the mouse.
Turn the mouse cover anti-clockwise to release the ball, remove the cover and take the ball out.
Use the soft tissue to clean the mouse ball, be sure to remove all dust/hair/debris.
Next, notice the 3 rollers within the mouse casing, these are what we need to clean.
You can improvise on how to clean the rollers, using your fingernail gets good results, if the mouse hasn't been cleaned before then you will see lots of dust on the rollers, whichever way you choose to clean them make sure you remove all traces of dust/debris as the smallest piece can cause the mouse to behave erratically.
When you have removed all traces of dust/dirt from the rollers and the ball is nice and clean, simply put the ball back in and replace the cover turning clockwise to lock it in place.
Plug the mouse back into your machine and turn the machine on, now your mouse should be as good as new.
Fragmentation is caused when an operating system breaks a file into pieces because there is not enough space on the storage device where the file was originally saved.
One example of this would be where a file was originally saved, then modified causing the file to be larger in physical space than first anticipated, the operating system will then break the file into 2 or more pieces and store them in different parts of the storage area.
The system would then keep a record of where the different partsof the file are stored; this is achieved through the use of a File Allocation Table (FAT) or similar file system such as NTFS.
Then, when the operating system requires the file again, it will query the file system (FAT/NTFS/or other) to find out where the different parts of the file are located on the partition (drive).
Defragmentation is the term given to the process of scanning the file system and rejoining the split files back into consecutive pieces.
The process of defragmenting can be time consuming, but it is one of the easiest ways to increase the performance of your PC, the frequency of which a PC should be defragmented will directly depend on the amount of usage.
Defragmenting in windows 98/ME
Before you start ensure you have enough time to complete the defragmentation process, it can be anything from 30 mins up to several hours depending on how much use the PC has had since the last defrag was completed.
To start the defrag utility, click on the Start button, then hover your mouse over Programs, then hover over Accessories, then hover over System Tools, then click on Disk Defragmenter.
Windows 98/ME will now ask you which drive you wish to defrag, select the drive you want to defrag (usually C:) from the pull down menu and then click the OK button.
The Defrag utility will then start defragmenting the selected drive as seen in fig below:
Note : - Sometimes the windows defragmenter that it cannot defragment the drive Because the drive has errors. if this is the case then run the Scandisk utility first,to
Defragmenting in Windows XP
First of all make sure you have enough time to complete the defragmentation, the amount of time will depend on how much use your PC has had since the last defragmentation.
To start the defrag utility, click on the Start button, then hover your mouse over all programs, then hover over Accessories, then hover over System Tools, then click on
Disk Defragmenter.
This will start the defrag utility, you will see the defrag dialogue box as shown in fig. below
The next step is to highlight the drive you wish to defragment (one left click on the drive), then click on the Analyze button, this will check the selected drive for fragmentation, the utility will then tell you whether the drive needs defragmenting or not.
If the drive needs defragmenting simply click the Defragment button, once clicked the utility will begin defragmentation of the drive, it may take a few hours depending on the size of the drive.
Once it is complete simply close the defrag utility.
All parts are fine,but the PC dosent boot
Take out all your sticks of RAM except for 1, and place it in the third slot. (Reading left to right). Boot up. You should get something on the monitor, if not, then we know it's not a memory problem.
Let's check the motherboard. Take out ALL OF YOUR RAM and boot up. If you are getting a loud, annoying beeping sound, you are getting post responses, and your motherboard works.
Video card? If you can take it out, not sure if you can cuz it's internal, but if you can, move it to the second PCI Slot. Just unscrew the screw connecting it to the back, and then pop it into the second slot. See a difference on your monitor?
Also try, to see if your monitor is in "Sleep Mode". Check this preferably in the Menu Options.
Hard Drive... check to make sure all cords are plugged in, and that there are no lose wiring.
As of your PSU... how many Watts are you running on? If you are only running on 120 watts or less, then, it may have shorted out by now.
If none of the above helps, go diagnose to see if your processor is fried with a computer technician.
You're saying that everything is functioning. Well if all your hardware is functioning, replace your monitor.

LCD (Liquid Crystal Display) Monitor LCD refers to the type of display, a Liquid Crystal Display works by having two layers of polarised material with liquid crystal in between, when an electrical current is applied to the liquid crystal molecules they become scattered allowing light to pass through.
Modern LCD displays use either passive or active (TFT) matrixes, the later producing a sharper image but at a higher cost.
LCD computer monitors are excellent when space is a problem due to their slim design.
CRT (Cathode Ray Tube) Monitor
Sometimes referred to as a conventional monitor, the technology used in these monitors is similar to that used in conventional TVs, whereby electrons are fired from guns through a vacuum to force the phosphor coating to light up.These types of monitor generally offer slightly better moving image quality than their LCD counterparts (especially the more economic LCDs).
Resolution
A monitor's maximum resolution refers to the maximum amount of pixels that it can display, the higher the number, the smoother the image will appear.Dot Pitch / Pixel Pitch
The image on a computer monitor whether it is CRT or LCD is made up of pixels (Picture Elements), dot pitch and pixel pitch refer to the space between the pixels on CRT and LCD monitors respectively.The figure for example 0.26mm would mean that each pixel is 0.26mm apart, the smaller the gap between each pixel the better the quality of the image.

The price of a personal A4 Laser starts at around £65 ($130 USD apx) for a monochrome (black & white) printer and between £190 ($380 USD apx) up to £400 ($800 USD apx) for a colour machine. The cost of producing an A4 text page is around 1p ($0.02 USD apx) with a combined colour graphics and text page at around 2p ($0.04 USD apx).
As you can see, the difference in purchase price is offset by the cost of each print - with the laser producing an A4 page at up to a tenth of the cost of an inkjet print.
Laser printers therefore are much cheaper to run than an inkjet, and will excel at the printing of text and solid colour graphics - reports with logo's and charts for example. However, the machines in the scope of this article can not output a photo realistic print to the same quality as an inkjet.
| Inkjets are more expensive to run than a laser, but they produce high quality prints of all types. They can also be found in this price range with the ability to print on CD's and DVD's, to be networked to other computers, and to print directly from cameras, mobile phones and data cards without even having to turn on your PC.
If you want a good all round printer that will give you exceptional quality, and you do not produce large amount of prints then the inkjet is the right choice for you. There are a few situations in which a home user may consider the purchase of a laser, maybe even as a compliment to a good inkjet photo printer - for example: You are involved with a local society, sporting group or similar, and are tasked with sending out a monthly newsletter to the other sixty members. Or, you run a small business, and want to regularly send out mailers and information to the 500 customers in your database. |
|
You love the quality of the photos produced by your inkjet, but you want to run off lots of prints - maybe of a holiday or event for friends and family. Batch printing on a personal inkjet printer is expensive. Consider using an online printing service. These will provide the same high quality prints at 6x4 inches at a fraction of the cost - and deliver overnight from your e-mailed files.
Are there any other choices for me?
There are other printer technologies in the marketplace but these all appear on the larger machines for office use. However, there is one more solution to consider. If you have limited space in your home 'office' - take a look at an 'All-in-One' device. For a small premium over the corresponding printer, these machines incorporate a printer and scanner in the same footprint - and offer the facilities of a Printer, Scanner, Photocopier and Fax. For the price these are really amazing value, and offer the home user a feature rich package in a compact uni
Printer Specifications and Features
In order for you to make an informed choice, below we have compiled some of the terms that are used when advertising printers along with an explanation:
DPI - Dots Per Inch (Resolution)
This is a measurement commonly used to describe the quality of printers and it refers to how many pixels per square inch that it is able to print - the higher the DPI - the smoother the quality of the image. In the early days of the personal inkjet this used to be very important, but nowadays even the cheapest machines can work at very high DPI. In fact, the highest resolutions are only used for producing photographs - and you will find settings in most printer software that enable you to lower the quality of the print, for say, producing a letter or homework report. Everyday tasks like these do not require the highest resolution settings of the modern printer to look good. REMEMBER - the higher the DPI setting, the more ink you are using!
PPM - Pages Per Minute
This describes how many pages the printer is capable of producing in one minute, this is normally quoted with separate figures for monochrome and colour pages.
USB - Universal Serial Bus
This refers to the interface (connection type) the printer uses to transfer data between it and the PC. USB is now the universal type of wired connection for personal printers, with the installation usually being a matter of simply plugging it in, inserting the manufacturer's disk and off you go.
Media Slots and TFT Screens
Many printers now offer built in media slots in which your camera data card can be inserted. The images can be viewed on a small integrated TFT screen which allows the facility to rotate and crop the image. Make your adjustments and press the print button - all without turning on your PC! Make sure the printer you choose has the correct slot for the media card your camera uses.
PictBridge Port
This port will allow a direct wired connection from a PictBridge compatible digital camera, and enable you to print directly from the image chosen on the camera's screen. Again your PC does not have to be turned on.
Ethernet port and wireless adapters
Many households now have more than one computer. These types of interfaces allow the sharing of one printer between two or more PC's - in the case of the Ethernet port by a wired connection to a home network 'hub' - or even better by a wireless adaptor which works in the same way as a wireless connection to the internet. Ethernet ports are usually built into the printer. Wireless adapters are usually an extra available at additional cost - if required, look for these on the specification when buying the printer.
Bluetooth & IrDA (Infra-red)
Look for these interfaces if you want to print photographs direct from your mobile phone embedded camera. The interface may be via an adapter available at extra cost.
Multiple (paper/media) input trays
These will allow the user to keep the printer loaded with the most commonly used paper types, for example - 6x4 inch glossy media for photographs and A4 plain paper for letters and reports. The input trays can be selected manually or be automatically engaged when the print settings are chosen by the user.
CD/DVD printing
Very useful if you like to produce CD's or DVD's, maybe containing photo's or movie footage for friends and family. The facility allows a CD/DVD to follow a straight path through the print platen of the computer and an image of your design can be applied to printable discs.
