that will fix an erroneous

error message.)

Determine if hard drive is giving correct

error message. Run the Drive Protection

System text if applicable.

Apply firmware patch if applicable. (see

www.hp.com/support

)

Back up contents and replace hard drive.

Check that computer air vents are not

blocked and cooling fan is running.

Verify processor speed selection.

Replace the processor.

Replace the system board.
