Healthy hardware
Whilst you can keep the files on your hard drive in good working order using programs that come with DOS, and whilst viruses can be kept at bay with good software, it's down to good old-fashioned hands-on cleaning when it comes to maintaining the screen, switches, keys and cables that make up your PC. Keeping the hardware clean can prolong the life of your computer and make sure it's running at its best.

There are parts that regularly come in contact with the grime on your hands and in the air, and others that are hidden away and get dusty. Always remember to shut off the computer before you begin. For the area around the drive, printer, cables, and the back of the screen, carefully use the hose attachment of your vacuum cleaner to get rid of dust and to unclog vents. Wipe all plastic casings with a microfibre cloth slightly dampened with an alcohol-based cleaning agent.

For the screen itself, wipe with a soft cloth (kitchen paper is too rough). If smudges remain, dampen the cloth slightly with distilled water (dilute alcohol is OK if it's an LCD screen, but be careful). Never spray cleaning agents directly onto the screen.

Turn the keyboard upside down and give it a gentle shake. You'll be surprised at what comes out - did you really eat biscuits and toast that often while you were working? Use a soft clean brush (an old make up brush or paintbrush works well) to push out bits that are stuck up under the keys, then turn the board back over and wipe the keys with a cloth dampened with an alcohol-based cleaning agent. Use damp cotton buds to get into all the cracks and remove grime.

Finally, don't forget the mouse! Dirt and dust can make a mouse misbehave, and stick when it shouldn't. Unscrew it from underneath and clean the ball and plastic ring thoroughly with a soft cloth or cotton wool balls dipped in vinegar. Dry it well before reassembly.

Now leave everything to dry completely before switching back on. Go and have a lie-down - you deserve it!

Devising a Family Code for internet use
Buying a PC is easy; helping your children put it to constructive use may not be. A simple timing rule of an hour (or less) shared between the TV and the PC may help, but many parents have gone one step further and have devised a Family Code. This is a set of rules for internet use, drawn up in consultation with all computer-using family members. For a framework to help you get started on your own Family Code, go to ParentsCentre.
