HP Hardware Diagnostics
HP Hardware Diagnostic Tools is a hardware diagnostic program that is preinstalled on your computer.
Use it to test computer hardware and troubleshoot computer issues.

Step 1: Before you begin

Close all programs and turn off the screen saver. Most of the tests take only a few minutes to complete,
however, some tests may take longer and use a lot of system resources. Turning off non-essential
applications helps the tests run more efficiently.
NOTE: Hardware Diagnostic Tools provides a lot of information. For best results, read and follow the
instructions as they are displayed. The instructions may be displayed before, during, and after the tests
are run.

Step 2: Start Hardware Diagnostic Tools

Click Start > All Programs > PC Help & Tools > Hardware Diagnostic Tools. A window opens and
displays a message to close all applications. Close all non-essential applications and click OK to
continue.

Step 3: Check Alert Messages

Hardware Diagnostic Tools scans the computer for any disabled or misconfigured devices. Detected
issues are displayed in the Alerts section at the top of the main page. Always check the Alerts first, as
the computer issue may be related to an alert.
1. Click Alerts and review the messages.
If no alerts are displayed, go to Step 4 to start testing.
2. The first alert is usually a reminder to record a bootable diagnostic CD. In case the computer is
ever unable to start, the bootable CD can be used to open Hardware Diagnostic Tools to help
diagnose the problem.
Do one of the following:
●
Click Record Bootable Diagnostic CD and follow the on-screen instructions to create a
bootable CD. If you want to record the CD another time, click Next or Done.
●
Click Next to read the next alert.
