  1. Windows-based Macintosh-based Computer Trouble Shooting: Nightmares Versus Challenges By Ernest Lewis, CTAP, Kern County, Level III TechMentor

  2. Proficiency #1.8 Implement basic trouble-shooting techniques for computer systems and related peripheral devices before accessing the appropriate avenue of support.

  3. Windows-based No Power Will Not Boot Weird or No Images on Screen Macintosh-based No Power Question Mark Flashing (Will Not Boot - Sad Computer Icon Extension Problems Screen Appears Discolored Common Problems

  4. Macintosh-based See Windows-based Suggestions. Windows-based No Power - (Outside) Check the power cord and/or surge protector. Check all switches (zero is off and one is on). No Power - (Inside) Check Main Power Cable to Motherboard. Check Transformer.

  5. Windows-based Will Not Boot • Check to see if a non-system disk is in the floppy drive (A:). • Make sure that a bootable floppy is handy. • Press F8 or the control key and choose Safe Mode. • Reinstall system only if there is no other hope. Macintosh-based Will Not Boot • Turn off extensions and try again (hold down the Shift key at startup). • Have a current system’s disk handy (CD and/or floppy). • Inspect the status of the hard drive with the disk utility file that is provided with the OS disk.

  6. Macintosh-based Will Not Boot (continued) Clear the *PRAM by pressing the Apple key, option, P, and R keys at the same time. Check the computer’s battery condition. Reinstall new system folder if necessary. *PRAM: Parameter RAM (battery memory) helps maintain the date and time. Note: If you use a network connection at your school and/or office, you will have to set AppleTalk back to Ethernet. The default setting returns to Printer after the PRAM is cleared.

  7. Windows-based • Weird or No Images on the Screen • Check connections. • Make certain the the correct video driver is installed. • Check to see if you have enough video memory to display a given screen size or amount of colors. • Check monitor settings. • Check video card and/or video card slot. • Use the Help application in Windows. • Macintosh-based • Weird or No Images on the Screen • Check connections. • Check monitor settings. • Check video card and/or video card slot. • Tap on the space bar to see if the computer is “sleeping.”

  10. Quick Suggestions • Do not be afraid to make a mistake but use common sense. • Research the Web for answers to your questions. • Check locally for computer classes. CTAP is an excellent resource. Also, one can call CompUSA at (661) 322-2122. • De-static yourself before working on electrical items. This can be done by discharging yourself on the unit’s case prior to working on it or, preferably, by wearing a special copper wrist band that is attached to the unit’s case. • Avoid wearing only socks and plastic shoes on a carpeted surface. Static will surely build. • Join a computer club, such a KIPUG, Kern Independent PC Users Group - see <http://www.kipug.org> for details.

  11. Quick Suggestions continued • Visit How Stuff Works at <http://www.howstuffworks.com/> to gain a theoretical knowledge and the like. • Keep abreast of the ever-changing computer field by studyingPC World Online at <http://www.pcworld.com/>. • Investigate new and old technologies on Cnet.com at <http://home.cnet.com/>. • Take a peek at Frank Condron’s World O’Windows at <http://www.worldowindows.com/win98.asp>. • Take a gander at the official site for Mac OS at <http://www.apple.com/macos/>.
