3 Troubleshooting Your PC

If Your PC Does Not Start Properly

If You Cannot Start Your PC from a Modem

If you are running Windows 95 and you have chosen the option to start your PC from a modem, and this option does not work, then you need to change the IRQ setting in the HP Setup program.

In the Setup program, go to the Security group, and the “Start-up Center” submenu. Change the IRQ setting for the setup item “Start from Modem”. (Refer to "HP Setup Program", on page 66.)

If a POST Error Message is Displayed

The Power-On-System-Test (POST) can detect both an error and a change to the configuration. In either case, an error code and short description is displayed. Depending on the kind of error, you will have one or more of these choices available on screen:

•Press to ignore the message and continue.

•Press to run Setup and correct a system configuration error. HP recommends that you correct the error before proceeding, even if the PC appears to start successfully.

•Press to accept (validate) the change and update Setup’s configuration information.

•Press to see more details about the message. After viewing these details, you will be returned to the original POST display screen. If the message is actually a change to the configuration you have made (for example, you have just removed some memory), you

can then press to accept the change and update Setup’s

configuration information. Otherwise, press to ignore the

message and continue, or press to run Setup and correct a system configuration error. (The number of choices you will have available are dependent on the kind of error.)
