Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Computer Repair FlowchartsBy RickSept 5 2009 UPDATE TO POST: The author of these flowcharts, Morris Rosenthal, expressed concern about having his copyrighted material shown here.
The most comprehensive of these flowcharts is the Boot Failure Troubleshooting Flowchart which encompasses several smaller flowcharts. Power Supplies commonly break, especially if they are hit by a power surge (too much power, such as when hit by lightning), blackout (no power), or brownout (lower voltage power). RAM problems can be vexing because they might only appear when a particular part of the RAM is accessed. This flowchart assumes the use of IDE hard drives, which are older than the standard SATA drives in today’s computers. Again, this chart assumes that you are using an IDE connector, not today’s standard of SATA drives. These video card diagnostics assume that you are using a discrete video card, not a motherboard with integrated video which are common in today’s lower cost computers.
This is another case where it is useful to have other computers available to determine if the problem is related to the network (cables, router, switch) or the computer. They remind me very much of the fantastic IBM Field Engineer handbooks from the late 70’s.
Other times, more serious repairs may involve replacing the internal power jack on the motherboard.


If you’re interested in following the diagnostic process of computer repair specialists, take a look at these flowcharts by Morris Rosenthal. You can see that it is PC focused, asking you to run scandisk and FDISK on your hard drive. Be sure to get a high enough wattage power supply, especially if you have a power hungry graphics card. This can manifest itself through strange computer behaviors that are often mistaken for viruses. Without replacement parts, it can be difficult to determine where the problem lies between these three components.
Many of today’s laptop hard drives have accelerometers built-in so that they can protect the hard drive when you are moving the laptop. Bad hard drives and CD drives might actually sound bad, with grinding, straining, or clicking noises.
These may be fixed with new drivers, or might (for older IDE drives) require you to remove or change the setup of other devices.
New computers often ship with a driver problem or needed updates that are easily fixed by searching Google or the knowledge database of the computer manufacturer. If I’m not mistaken, this is the chart used by our tech support team in our institution. Every mainframe operator worth his saalt had bribed his local CE (customer engineer) for a copy. Many of our customers come looking for used Windows laptops because they use software that is compatible or works best with Windows XP.


Please see his Computer Repair with Diagnostic Flowcharts site for the full examples of his flowcharts or purchase his Computer Repair with Diagnostic Flowcharts book from Amazon. With that book and the field repair kit (6 large red trunks containing every card from the machine in question), you would be almost guaranteed to fix whatever the problem was Рeventually, just by following the incredibly detailed flowcharts that covered page after page. We are a large computer repair shop in the Edmonton area and many people come to us for quality refurbished laptops and desktops. Other customers buy a refurbished XP system for their parents, since they refuse to use anything else or they are wise and know that XP is a solid and reliable OS. We also take your old laptops as a trade in for a new refurbished computer from our store, see in-store for details.
Studies show annual hard drive failure rates to be 2-13%, depending on usage and particular model used. Over the next 5 years there is expected to be a transition to primarily using solid state drives (SSDs) that can potentially last longer and use less energy.
Where else would you be able to buy a quality refurbished laptop in the Edmonton area and get a warranty (extended warranty is also available).
