Part of Upgrading & Fixing Computers Do-It-Yourself For Dummies Cheat Sheet

Whether you’re upgrading or fixing a computer, a few basics apply no matter what. The No. 1 thing is to turn off your computer before you start tinkering with its parts. Check out these tips for any computer upgrade or repair:

  • Turn off and unplug your computer before taking off its cover. Please. This one’s the most important step before a computer upgrade or repair. You can damage both yourself and your computer if you forget to turn off and unplug the computer.

  • Install computer parts one at a time. Always make sure the first part works with your version of Windows before installing the next computer part.

  • The red (or colored) wire is positive. The red (or colored) wire often plugs into the pin or socket marked by a little + sign.

  • The positive/red wire connects to Pin 1. When you upgrade or repair to a computer part by swapping an old part for a new one, you may need to connect a wire to a pin. Look for little numbers printed along the edge of a socket. Can’t see the number 1? Then push the plug into the socket with the red wire facing toward the low numbers on the socket.
