Running the Diagnostic CDWhen your computer starts to show some trouble by slowing down or degradation of service and loud noise, you can pinpoint the source of the problem by using a computer diagnostic utility. When you buy a new computer, it comes with a diagnostic utility. You can start diagnosing by inserting the diagnostic tool CD into the CD/DVD bay. You can run it at boot up or navigate inside the CD and then run the diagnostic tool by clicking on it. - The diagnostic utility runs for a period, looking at all the partitions, drives and folders of your computer. It also looks at the registry and the incompatibilities of programs installed. While the diagnostic runs, it shows a status of the scan. Then, at the end of the scan, it will show a summary of the scan providing a detailed log. The utility can pinpoint possible sources of problems, like a recent hardware installation, an upgrade of CPU, a new program installed and performance issues. You can let the diagnostic run on its own and leave it, in some case you can even do your work while you leave the program running in a minimized window. However, it would probably be best if you let it run without interruption in order to isolate problems without adding more to them.

Examining Event LogsDetails from the diagnostic utility logs provide important information to diagnose the symptoms and problems on your computer. Defragmenting and increasing available disk space are two examples of possible fixes to some of the commonly diagnosed problems when a computer slows down and makes noise. Double-check findings with the performance monitor and task manager. Look at what processes are running and how the computer performs when those run. Look at the event logs of your computer to determine the error codes and then find possible solutions on the errors you find. -
Fix ProblemsThe computer diagnostic utility will provide suggestions not only to further troubleshoot to diagnose the problems but it can fix the problems it finds. Some advanced computer diagnostic utilities give a computer user in the end the options to resolve those problems. The user can simply click on the option and the diagnostic utility will run the fix. Some fixes, however, may need another software or tool. This is especially true after addition of new hardware or after a recent upgrade, and it may be necessary to remove the new hardware or back out the changes back to the last known good configuration.
