Solving Problems 171
• After you have checked the software installation diskettes or CDs with
a virus-scanning application program, you should disable the virus-
scanning 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.
