Solving software problems

Most software problems occur as a result of the following:

●

The application was not installed or configured correctly.

●

There is insufficient memory available to run the application.

●

There is a conflict between applications.

●

Be sure that all the needed device drivers have been installed.

●

If you have installed an operating system other than the factory-installed operating system, check to be

sure it is supported on the system.

If you encounter software problems, see the applicable solutions listed in the following table.

Computer will not continue and the HP logo does not display.

Cause

Solution

ROM issue - POST error has occurred.

Observe the beeps and LED lights on the front of the computer.

See Appendix A,

POST error messages on page 116

to determine

possible causes.

See the Worldwide Limited Warranty for terms and conditions.

Computer will not continue after HP logo screen displays.

Cause

Solution

System files may be damaged.

In Windows 7, use recovery media to scan hard drive for errors, or

use Windows Startup Repair to fix problems that might prevent

Windows from starting correctly. Windows Startup Repair is one

of the recovery tools in the System Recovery Options menu. You

can also create a system repair disc that contains the System

Recovery Options menu. If the problem is severe enough that

Startup Repair doesn't start on its own and you can't access the

System Recovery Options menu on your computer's hard disk,

you can get to the menu and start Startup Repair by using the

Windows installation disc or a system repair disc that you created

earlier.

In Windows 8, use Automatic Repair to fix problems that might

prevent Windows from starting correctly.
