calling for technical support.
●
Run the HP diagnostic tool.

Run the hard drive self-test in Computer Setup.

Check the power light on the front of the computer to see if it is blinking red. The blinking lights are
error codes that will help you diagnose the problem.

If you are working on a network, plug another computer with a different cable into the network
connection. There might be a problem with the network plug or cable.

If you recently added new hardware, remove the hardware and see if the computer functions
properly.

If you recently installed new software, uninstall the software and see if the computer functions
properly.
