If your HP desktop computer fails to turn on, start, or boot, follow the detailed troubleshooting steps for desktop boot below:

Initial Precautions and Hardware Reset

  1. Verify Power Supply: Ensure that the power cable is properly connected and the power outlet is functional.

  2. Perform a Hard Reset:

    • Turn off the computer.
    • Disconnect the power cable.
    • Remove all external devices (printers, external hard drives, USB drives) except for the mouse, keyboard, and monitor.
    • Press and hold the power button for about 20 seconds.
    • Reconnect the power cable and turn the computer back on using the power button.
     

Diagnosis and Next Steps

  1. Does the Computer Turn On?
    • If No: The computer may not be receiving power. Consider setting up a repair.
    • If Yes: Proceed to reconnect external devices one by one to determine which might be causing the problem.

Hardware Test and Windows Not Starting

    • Turn it back on and repeatedly press esc until a menu appears.
    • Press f2 to access the HP PC Hardware Diagnostics (UEFI).
    • Run the Fast Test and then the Extensive Test if no issues are detected initially. Document any failure IDs for customer support.

Resetting Windows Using Recovery Environment

    • Restart your computer and press the f11 key repeatedly to open the Windows Recovery Environment.
