All hard drives can fail. If a hard drive fails, recovering data is unlikely and expensive. So having a back up of the important data in your computer is essential, particularly those which are irreplaceable such as family photos or work documents.
How do I backup my data?
Most common devices used for a backup are:
- External Hard Drives are great for general use. You can use them over and over again, they usually have quite a lot of space, and they are good for backing up large amounts of data. Remember that external hard drives can fail too so make sure you keep the copy on your computer.
- CD’s and DVD’s are also good mediums for backing up data, and are reasonably cheap if you just want to backup a few things like your photo collection, music and documents.
- USB Flash Drives are great ways of storing small amounts of data, like work documents, etc.
A Backup is essentially just a copy of the data you backup, so the simplest way of backing up is just copying the data and pasting it in the device you want to backup to. There is also software that will do this for you automatically. Read the rest of this entry »

Your processor is like the brains of your computer it does the calculations.
It”s common for processors to use a large amount of processing power for short periods of time when loading software. That is why the more programs you have programmed to load on start-up, the longer it takes to start up .
Scenario
You have six programs that load at start up, and all require 6 seconds loading time. That is roughly 30 seconds longer than if you had only one program loading at start-up. Generally as a computer gets older the owner will install more programs . Many of these load on start-up because software makers often program their software to load during start-up to try and make people use their software more.

The easiest way to do this is by using msconfig.exe, a utility that allows you to control a number of settings on your computer.
Turn on “msconfig.exe” in Windows XP
1. Press the “start” button in the bottom left hand corner
2. Select the program “RUN” and turn on.
3. Type in “msconfig” then press enter
To turn on msconfig.exe in Windows Vista
1. Press the “Windows” button in the bottom left hand corner
2. Type in ‘msconfig’ in the search field then press enter
A window should pop up with ’system configuration’. Select the “Startup” tab
Uncheck the boxes of the programs you don’t want to load during start-up, click the apply button in the bottom right hand corner then ok. The next time the computer starts up it should be a lot faster!
If you don’t know what a program does, don’t turn it off! You can do google searches on programs if you want to know what they do.

Memory is like short term storage for the computer. Everything that is running is stored in the memory to be used by the processor.
All of your programs use up memory. The more programs you have running at one time, the more memory it will use. However, using up memory won”t actually slow your computer down until you run out of memory.
Scenario
An old computer has 256MB of RAM. This computer is running Windows XP which uses about 200MB of RAM itself. This leaves only 56MB of free RAM. If you open MSN Messenger, Microsoft Word, and Internet Explorer these programs combined will use 157MB. This creates 357MB of RAM, being used by a computer which only has 256MB of Ram.
In this situation the computer will use the Hard drive (long term memory), as replacement for RAM. Since the hard drive runs a lot slower than RAM the computer will start to run slowly.
However, if you have 2048MB (2GB) of RAM and you only use 357MB then your computer will run fine until you use more than 2048MB of ram.

Contrary to what most people think. A graphics card has absolutely no effect on your experience in watching movies and DVD’s on your pc. You can actually watch movies in the highest quality with most graphics card even some onboard graphics cards.
Many people have the idea that to watch HD (high definition) videos you need to splash out and buy an expensive card. Not true at all! All onboard graphics cards sold by Spanner Box are HD compatible.
This is because all the frames in a movie have already been created and rendered before you watch it. The function of a graphics card is to render 3D graphics and animation on the spot as it is being displayed. Think of movies as a roll of film being played and your PC is just displaying pre-rendered frames.
Graphics cards become essential predominantly with graphic intensive programs such as Gaming, 3D CAD work and Video Editing. (all Sbox computers are pre-equipped with 1080p Full HD at the lowest level, so you don’t have to worry!).

Surprisingly this is not true. A Computer can actually technically run as fast as it did when you first opened the box, as long as it is treated and maintained in the correct way. Usually a computer gets slower as you continually install programs on your computer that have services that are run on Start Up. Your Computer, (like most people I know), becomes slow the more things it is asked to do at once. Also newer programs tend to be more performance hungry as they generally have more features and assume a more modern computer.
It helps to know everything your computer is doing. If your computer is slow, right click the ‘Start Bar’ and select ‘Task Manager’. This should give a list of all the processes and programs that are eating up all your systems power.
