Perform Windows Computer Preventive Maintenance

Fixing your own computer is less necessary if you perform computer maintenance. These tips for maintaining your PC can help you prevent computer problems before they happen and can keep your computer running smoothly and efficiently.

Be aware of hygiene and updates

  • Keep your computer cool and dry. Avoid direct sunlight on all computer components. Don’t block fan and ventilation openings. Be careful with food and drink around the machine; a spill can ruin a machine in seconds.

  • Keep your computer clean. Wipe the monitor, keyboard, and computer case periodically with a soft cloth. Keep handy a soft, clean paintbrush or a can of compressed air to clean out the keyboard and ventilation ports on the computer case and monitor. You can also gently vacuum the parts.

  • Keep your software up to date. Microsoft regularly updates Windows. Other software manufacturers keep their applications current with updates, too. Check manufacturer Web sites.

Be aware of sights and sounds

  • Cooling fan. The computer’s cooling fan should make only a soft whir, but some machines automatically speed up the fan when temperatures start to rise. Is the computer in direct sunlight? Have you inadvertently restricted airflow in and out of the box? Is the power supply overheating?

  • Hard drive. A louder-than-usual hard drive may mean an impending failure; listen for clicks or erratic speedups and slowdowns. Back up your data and run diagnostic programs provided by the hard drive manufacturer or your computer maker.

  • Lag time. Notice how long it takes to launch a program or retrieve data. If things start taking unusually long, you may be seeing a hard drive about to fail, or it just may be cluttered. Run diagnostics and use a defragmentation utility Also, keep an eye out for error messages or alerts.

Get Help with Computer Problems

Having trouble with your PC? Computer help comes from many sources: the manufacturer and local computer stores are just two. The Windows Remote Assistant lets a friend or trusted expert control your machine and attempt repairs; remote assistance is available from hardware manufacturers and software companies.

  • Contact the manufacturer. For hardware problems and software that came installed on your computer, the manufacturer is the best place to start. Write down the computer model, serial number, and date of purchase; then check your documentation or the manufacturer’s Web site for contact information. Choose Start→Programs→All Programs and look for a folder named for your computer or manufacturer. Some manufacturers include complete user manuals or even videos to help you learn about your machine and troubleshoot it.

  • Find local experts. Many computer stores and big stores offer in-store repair. Make sure you are clear on the services they will provide and what it will cost before agreeing to service. Ask friends and co-workers for recommendations or references.

  • Use Windows Remote Assistant. Know somebody who might help, but they aren’t nearby? Microsoft includes a useful utility called Remote Assistant in current versions of Windows.
