After System Has Been Running Correctly

Problems that occur after the system hardware and software have been running
correctly often indicate equipment failure. However, many situations that are easy to
correct can also cause such problems. If you have problems after the system has been
running correctly, check the following:
T
If you are running the software from a diskette or CD-ROM, try a new copy of the
software.
T
If you are running the software from a hard disk drive, try running it from a floppy.
If the software runs correctly, there may be a problem with the copy on the hard
disk. Reinstall the software on the hard disk drive and try running it again. Make
sure all the necessary files are installed.
T
If the problem recurs, you may need to reformat the hard disk drive. The hard disk
drive, the drive controller, or the system board may be defective.
T
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.
T
If you suspect that a transient voltage spike, power outage, or brownout might have
occurred, reload the software and try running it again. Symptoms of voltage spikes
include a flickering video display, unexpected system reboots, and the system not
responding to user commands.
Note:
drive. If you are experiencing voltage spikes on the power line, install
a surge suppresser between the power outlet and the system power
cord.
