hardware configuration doesn't match the information recorded by the System Setup
program options, an error message may appear on the display.
To fix this problem, correct the appropriate options in the System Setup program. See
Appendix B, "Using the System Setup program," for detailed information about the
System Setup program and its options.
If, after checking the setup options, you have not resolved the problem, see "Running
the Dell Diagnostics" found later in this chapter.
Because most computers have several application programs installed in addition to
the operating system, isolating a software problem can be confusing. Software errors
can also appear to be hardware malfunctions at first. Software problems can result
from the following circumstances:
Improper installation or configuration of a program
Input errors
Drivers that may conflict with certain application programs
Memory conflicts resulting from the use of terminate-and-stay-resident (TSR)
programs, such as drivers
Interrupt conflicts between devices
You can confirm that a computer problem is caused by software by first running the
System Board Devices device group as described in "Running the Dell Diagnostics"
found later in this chapter. If all tests in the device group complete successfully, the
error condition is most likely caused by software.
The following subsections provide general guidelines for analyzing some software
problems. For detailed troubleshooting information on a particular program, see the
documentation that accompanied the software or consult the support service for the
software.
When you obtain software, check it for viruses using virus-scanning software before
installing it on the computer's hard-disk drive. Viruses can quickly use all available
system memory, damage and/or destroy data stored on the hard-disk drive, and
permanently affect the performance of the programs they infect. Several commercial
virus-scanning programs are available for purchase, and most bulletin board services
(BBSs) archive freely distributed virus-scanning programs that you can download with
a modem.
Before installing a program, read its documentation to learn how the program works,
what hardware it requires, and what its defaults are. A program usually includes
installation instructions in its accompanying documentation and a software installation
routine on its program diskettes.
