Problems After the System Has Been Running
Correctly
After the system hardware and software have been running correctly,
problems often indicate equipment failure. Go through the checklist below
to see if the situation is one that may be easily corrected.
If the problem recurs after you have checked and corrected all of these items,
refer to the troubleshooting procedures (see "Troubleshooting Procedure" in
this chapter).
___ If you are running the software from a diskette, try using a new copy.
___ If you are running the software from a hard disk, try running it from a
diskette. If the software runs correctly, there may be a problem with the
copy on the hard disk. Reinstall the software on the hard disk and try
again. Make sure all the necessary files are installed.
___ Try clearing CMOS RAM (Chapter 5) and running Setup (Chapter 3).
___ 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.
___ A transient voltage spike, power outage, or brownout may have
occurred. Symptoms of voltage spikes include a flickering video
display, unexpected system reboots, and the system not responding to
user commands. Reload the software and try again.
___ Voltage spikes can occasionally cause the heads of the disk drive to
contact the disk. This can corrupt or destroy data files. If you are
experiencing voltage spikes on the power line, install a surge suppresser
between the power outlet and the system power cord.
___ Try reseating the SIMMs.
