1.10 Problems After 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.
Use this checklist:
If you are running the software from a diskette, try a new copy of the software.
■
If you are running the software from a CD-ROM disk, try a different disk to see if
■
the problem occurs on all disks.
If you are running the software from a hard disk drive, try running it from a
■
diskette. If the software runs correctly, there may be a problem with the copy on
the hard disk drive. Reinstall the software on the hard disk, and try running 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 might
■
have occurred, reload the software and try running it again. When voltage spikes
or brownouts occur, symptoms include a flickering video display, unexpected
system reboots, and the system not responding to user 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
above symptoms that might indicate voltage spikes on the power line, install a surge
suppressor between the power outlet and the system power cord.
