Booting your HP computer into diagnostic mode is possible in a number of ways. The diagnostic mode of an HP computer is the same as the diagnostic mode for virtually any Windows computer. It is called "Safe Mode" and is available both in standard graphical format and in command line format to allow you to enter commands directly into the computer.
Click the "Start" button and type "Msconfig" into the "Search" field. Press "Enter." The "Selective Startup" window opens. Note: Windows XP users should click "Run" and then type "Msconfig." Then press "Enter."
Select the "General" tab and click the check box next to "Diagnostic Startup." Select the "Boot" tab and click the check box next to "Safe Boot." Click "OK." You will be asked to restart your computer. Click "Restart now." The computer will start up in diagnostic mode.
Repeat step 1 once you are finished with diagnostic mode. Repeat step 2, but this time unchecking the check box next to "Diagnostic Startup." Again, you do this once you are done with diagnostic mode.
Tips & Warnings
- You can also access the diagnostic mode of your computer by pressing the "F8" button as the computer is starting up. Continue to do so until the "Selective Startup" menu appears. Use the arrow keys to select "Safe Boot." If you need to access the command line version of diagnostic mode, select "Command Line" instead.
- Be sure to remove the diagnostic start-up mode by following step 3. Failure to do so will leave the computer starting up permanently in "Safe Mode" and some programs will not work properly when you use that feature.
