• After you have checked the software installation diskettes or CDs with a virus-scanning application program, you should disable the virusscanning application program before installing the software. You should also disable any other application programs that are "hidden," or operate in the background. • Verify that the program's device drivers do not conflict with certain application programs. • Confirm that a problem is software-related by running the System Board Devices tests in the Dell Diagnostics. If all tests run successfully, the error condition may be related to a software problem. • Ensure that the use of terminate-and-stay-resident (TSR) programs has not resulted in a memory conflict. • Remove or confirm the possibility of a program conflict by rebooting your computer system. • Ensure that a hardware conflict does not exist between devices. Operating System Compatibility Ensure that the computer's operating environment is set up to accommodate the application programs you use. Whenever you change the operating environment parameters, you may also affect the successful operation of the application programs. Sometimes, after modifying the operating environment, you may need to reinstall a program that no longer runs properly. Input Errors If a specific key or set of keys is pressed at the wrong time, a program may give you unexpected results. See the documentation that came with your application program to ensure that the values or characters you are entering are valid. S o lv ing Pr o ble m s 171
