Copyright 2009 by Morris Rosenthal -All Rights Reserved contact infoThis page offers links to flowcharts for PC diagnostics, excerpted from my book. The non-active links are for charts that are included in the book but not available online. The published book contains seventeen flowcharts for computer diagnostics plus a short text for every chart expanding on the decision points. The troubleshooting process is the same for an expensive Sony or IBM, or a downmarket eMachines or Gateway. Dell and HP (who purchased Compaq) manufacture PC’s in a wide range of price points, but you have to go through the same troubleshooting steps for the cheap ones as the expensive ones if you want to correctly identify and repair the failure.
