Solving Problems 161
• If you are running the software from a CD-ROM disk, is the disk
scratched or dirty?
• If you are running the software from a hard disk drive, is the
software correctly installed? Were all necessary procedures
followed and files installed?
• Are the correct device drivers installed?
• Is the software correctly configured for the system?
• Are you using the software correctly?
• If the problems persist, contact the software vendor’s customer
service representative.
The System Has Been Running Correctly
Problems that occur after the system hardware and software have been
running correctly often indicate equipment failure. Many situations that are
easy to correct, however, can also cause such problems; sometimes the
problem stems from changes made to the system, such as hardware or
software that has been added or removed.
Checklist
• If you run the software from diskette, use a new copy of the
software.
• If you run the software from a CD-ROM, try a different disc to see
if the problem occurs on all disks.
• If you run the software from a hard drive, run it from a diskette. If
the software runs correctly, there is a problem with the copy on the
hard drive. Reinstall the software on the hard drive, and run it
again. Make sure all necessary files are installed.
• If the problems are intermittent, there may be a loose cable, dirt in
the keyboard (if keyboard input is incorrect), a marginal power
supply, or other random component failures.
• If you suspect that a transient voltage spike, power outage, or
brownout may have occurred, reload the software and run it again.
(Symptoms of voltage spikes include a flickering video display,
unexpected system reboots, and failure to respond to commands.)
Note:
If you are getting random
errors in your data files, they
may be getting corrupted by
voltage spikes on your
power line. If you are
experiencing any of the
symptoms that might
indicate voltage spikes on
the power line, you may
want to install a surge
suppressor between the
power outlet and the system
power cords.
