How to Install RAM

 If your computer slows down when you're working with large files or many programs at once, you might be able to improve performance by installing extra RAM (Random Access Memory - your computer's temporary operating memory). These instructions will work for the majority of machines built in the mid 1990s and later.

Instructions

1. • 1
     Determine what kind of RAM you need, and whether your computer has enough open slots to hold it. The new RAM should match the existing RAM's specifications and configuration.
     
   • 2
     Shut down the computer and leave it plugged into the surge suppressor.

     Disconnect all peripheral devices, such as the monitor, from the computer.
     
   • 4

     

     Remove the computer cover.
     
   • 5
     Ground yourself to the computer with professional grounding equipment like an anti-static wristband or hold a metal part of the chassis.
     
   • 6
     Remove any cards or internal components necessary to give yourself unobstructed access to RAM sockets.
     
   • 7

     

     Pick up your SIMM (single in-line memory module) or DIMM (dual in-line memory module) by the ends without touching pins or chips.
     
   • 8

     

     If adding a SIMM, find the notched end and turn the SIMM so that it is parallel to the existing RAM card(s). Insert the SIMM into the socket at a 30-degree angle. If adding a DIMM, insert the DIMM straight in so that it is perpendicular to the motherboard.
     
   • 9
     Use slight pressure to keep a SIMM from backing out while rotating the module to an upright position perpendicular to the motherboard.
     
   • 10
     Make sure the small holes on each side of a SIMM fit into holders.
     
   • 11

     

     Feel or hear retaining clips lock a SIMM into the socket; close the side clips on a DIMM.
     
   • 12
     Gently try to pull the module out to ensure it is locked in position.
     
   • 13
     Replace all internal components.
     
   • 14
     Leave the cover off and reconnect the monitor, keyboard and mouse.
     
   • 15
     Turn on the computer.
     
   • 16
     Check the amount of RAM by right-clicking the My Computer icon in Windows and choosing Properties. On a Mac, use the About this Macintosh command in the Apple menu.
     
   • 17
     If you don't see the right amount of RAM, turn off the computer and try "reseating" the SIMM or DIMM (take it out and put is back in) and reboot. If that doesn't work, call a technician.
     
   • 18
     Shut down the computer and disconnect the peripherals again.
     
   • 19

     

     Replace the cover and reconnect all the peripherals.
     

Computer Safety Procedures

 The idea of computer safety goes way beyond making sure your firewall is up when you are surfing the Internet. Each aspect of using a computer from how you sit to how you care for your computer has safety procedures that should be followed. Some can help you and your health, and others are designed to help you keep your computer in good working order for the long term.

 

1. Ergomonics

   • According to the University of Western Australia, ergonomics is the process of developing work habits that will not damage your joints, your eyes or anything else involved in using your computer. To reduce glare on the computer screen and stress on your eyes, keep the light source for your computer area at a 45-degree angle from your eyes. Your elbows should be even with the trunk of your body and your forearms should be at the same level as your keyboard when you are typing. Your computer screen should be just below your eye level so that you can easily look over the monitor every 15 minutes or so to reduce wear on your eyes. Get up and stretch at least once every hour while working on a computer.
     

   Internet Usage

   • Never surf the Internet without anti-virus software running in the background, and keep your anti-virus software updated at all times. Do not click on attachments to emails from people you do not know, and do not click on links in emails that ask you to confirm your log-in information. Only do online transactions with secure websites. Determine which websites are secure because the secure websites start with https as opposed to the standard http. Avoid clicking on free-offer banners on websites, and close your Internet browser when you are not using it.
     

   Maintenance

   • Clean your screen only with products specifically marked to clean your kind of computer screen. Wipe down your computer at least once a month to remove an possible dust buildup, and use cans of compressed air once a month to blow dust and debris out of the various vents on your computer. Perform hard-drive maintenance at least once a month, including the defragmenting and disc-scanning functions. Perform a removable media backup of your personal data and important files at least once a week.
