That error typically means the hard disk is failing, but it can also be caused by something interfering with the boot process.

To verify the situation, run the Diagnostics routine.  You can try the suggested F2 from the screen that gives the error message or use this method - 

Start tapping the Esc key BEFORE starting the PC and then press the start button.
Keep tapping the Esc key until a popup menu shows. Then pick Diagnostics from that popup menu, F2.
Report back with the results. Also need the PC model number.


I'm not an HP employee.
