Make sure the option card is not touching any other card or component on your main system board.

If you installed a PCI card in a PCI slot, check to see that the PCI options in SETUP are set correctly for your card. For more information, see “Configuring PCI devices” in Chapter 2.

An external device connected to the option card is not working correctly.

Make sure you are using the proper cable to securely connect the device to the card.

Memory Module Problems

The memory count displayed by power-on diagnostics or the SETUP program is incorrect.

You may have installed the SIMMs incorrectly. They may be the wrong type or speed, or they may not be inserted all the way or in the correct sockets. See “Installing Memory Modules (SIMMs)” in Chapter 4 for more information.

If you have installed a gold-plated SIMM in the sockets, the socket may have corroded slightly. Remove the SIMM and clean the gold-plated connector with a pencil eraser; then reinstall the SIMM.
