●

Verify that all cables are not loosely or incorrectly connected.

●

After installing a non-PnP expansion board or other option (such as a diskette drive), restart the
computer.

●

Are all necessary device drivers installed?

●

Have all printer drivers been installed for each application?

●

Have you removed CDs and USB flash drives before powering on the computer?
