| I'm a lazy guy. I think it's easier to prevent problems beforehand than it is to try to solve them after they occur. Let's face it even if you're able to fix a problem, you would have saved yourself a lot of grief if you could have avoided that problem completely. It pays to spend a little time on preventive maintenance now if it saves you hours of problem-solving and disaster recovery later. That said, let's look at some simple things you can do to reduce your chances of contracting computer problems. System Unit Your PC system unit has a lot of stuff inside everything from memory chips to disk drives to power supplies. Check out these maintenance tips to keep your system unit from flaking out on you: Position your system unit in a clean, dust-free environment. Keep it away from direct sunlight and strong magnetic fields. In addition, make sure your system unit and your monitor have plenty of air flow around them, to keep them from overheating. Hook your system unit up to a surge suppressor to avoid deadly power spikes. Avoid turning your system unit on and off too often; it's better to leave it on all the time than incur frequent "power on" stress to all those delicate components. However… Turn off your system unit if you're going to be away for an extended period anything longer than a day or two. Check all your cable connections periodically. Make sure all the connectors are firmly connected, and all the screws properly screwed and make sure your cables aren't stretched too tight, or bent in ways that could damage the wires inside. If you're really adventurous, open up the system case periodically and vacuum or wipe the dust from the inside. (Just make sure the system unit is unplugged at the time!) Using a can of "compressed air" is also a good way to blast the dirt out of your system. You should also "dust" the inside of your CD-ROM drive, and even use a swab or commercial cleaner to clean the laser lens.
Keyboard Even something as simple as your keyboard requires a little preventive maintenance from time to time. Check out these tips: Keep your keyboard away from young children and pets they can get dirt and hair and Silly Putty™ all over the place, and have a tendency to put way too much pressure on the keys. Keep your keyboard away from dust, dirt, smoke, direct sunlight, and other harmful environmental stuff. You might even consider putting a dust cover on your keyboard when it's not in use. Use a small vacuum cleaner to periodically sweep the dirt from your keyboard. (Alternately, you can use compressed air to blow the dirt away.) Use a cotton swab or soft cloth to clean between the keys. If necessary, remove the keycaps to clean the switches underneath. If you spill something on your keyboard, disconnect it immediately and wipe up the spill. Use a soft cloth to get between the keys; if necessary, use a screwdriver to pop off the keycaps and wipe up any seepage underneath. Let the keyboard dry thoroughly before trying to use it again.
Mouse If you're a heavy Windows user, you probably put thousands of miles a year on your mouse. Just like a car tire, anything turning over that often needs a little tender loving care. Check out these mouse maintenance tips: Periodically open up the bottom of your mouse and remove the roller ball. Wash the ball with water (or perhaps a mild detergent). Use a soft cloth to dry the ball before reinserting it. While your mouse ball is removed, use compressed air or a cotton swab to clean dust and dirt from the inside of your mouse. (In extreme cases, you might need to use tweezers to pull lint and hair out of your mouse or use a small knife to scrape packed crud from the rollers.) Always use a mouse pad they really do help keep things rolling smoothly, plus they give you good traction. (And while you're at it, don't forget to clean your mouse pad with a little spray cleaner it can get dirty, too. )
note  | If you have an optical mouse, you can skip these steps; there aren't any mouse balls to clean! |
Monitor If you think of your monitor as a little television set, you're on the right track. Just treat your monitor as you do your TV and you'll be okay. That said, look at these preventive maintenance tips: As with all other important system components, keep your monitor away from direct sunlight, dust, and smoke. Make sure it has plenty of ventilation, especially around the back; don't cover the rear cooling vents with paper or any other object, and don't set anything bigger than a small plush toy on top of the cabinet. Don't place any strong magnets in close proximity to your monitor. (This includes external speakers!) With your monitor turned off, periodically clean the monitor screen. Spray standard glass cleaner on a soft cloth (anti-static type, if possible) and then wipe the screen clean. Don't forget to adjust the brightness and contrast controls on your monitor every now and then. Any controls can get out of whack plus, your monitor's performance will change as it ages, and simple adjustments can often keep it looking as good as new.
Printer Your printer is a complex device with a lot of moving parts. Follow these tips to keep your printouts in good shape: Use a soft cloth, mini-vacuum cleaner, and/or compressed air to clean the inside and outside of your printer on a periodic basis. In particular, make sure you clean the paper path of all paper shavings and dust. If you have an ink-jet printer, periodically clean the ink jets. Run your printer's cartridge cleaning utility, or use a small pin to make sure they don't get clogged. If you have a laser printer, replace the toner cartridge as needed. When you replace the cartridge, remember to clean the printer cleaning bar and other related parts. Don't use alcohol or other solvents to clean any rubber or plastic parts you'll do more harm than good!
