When to Use the Dell Diagnostics

Whenever a major component or device in your computer does not
function properly, you may have a component failure. If you are
experiencing a problem with your Dell™ computer, perform the checks in
"Solving Problems" and run the Dell Diagnostics before you call Dell for
technical assistance. Running the Dell Diagnostics may help you to resolve
the problem yourself quickly without having to contact Dell for assistance.
If you are experienced with computers and know what component(s) you
need to test, select the appropriate diagnostic test group(s) or subtest(s). If
you are unsure about how to begin diagnosing a problem, see
Dell Diagnostics."
