Troubleshooting

If your computer does not start, check the following:

∙Are all the cables properly connected to the computer? (See “Connecting a Monitor” on page 5 and subsequent sections.)

∙If you have installed an add-in board, have you installed it correctly? (See “Installing Add-in Boards” on page 21.)

∙Is the voltage setting on the back panel set to 115 V, or 230 V if your power outlet uses that voltage? (See “Connecting the Power Cord” on page 8.)

If the computer starts, but nothing appears on the screen, check the following:

∙Is the monitor cable attached to the monitor port on the back of the computer? Is the monitor turned on? Are the brightness and contrast controls correctly adjusted? Check your monitor manual.

∙Is your software correctly configured for your monitor and video adapter? Check the software user’s manual.

∙If you installed an add-in video board, have you installed and configured it correctly?

If the computer comes on, but does not finish booting, check the following:

∙Are the Num Lock, Caps Lock, and Scroll Lock lights flashing? If so, type the user password (see “Using Passwords” on page 52).

∙Does the computer beep more than once when you turn it on? The computer might not be configured correctly. Run System Setup to fix the configuration (see “Configuring Your Computer” on page 41).

If the computer still beeps more than once, your computer may have a malfunction. Contact your AST reseller for assistance.

∙Does a configuration error message appear on the screen? If so, run System Setup to correct the problem (see “Configuring Your Computer” on page 41).
