Problems with Application that Ran Correctly
Earlier
Problems that occur after the system hardware and software have
been running correctly sometimes indicate equipment failure.
However, they can also be caused by file corruption or changes to the
software configuration.
Check the following:
• If you are running the software from a diskette, CD-ROM or DVD-
ROM, try a different diskette.
• Uninstall and reinstall the software. 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. Symptoms of voltage spikes include a flickering
video display, unexpected system reboots, and the system not
responding to user commands.
Random errors in data files: 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,
you may want to install a surge suppressor between the power
outlet and the system power cord.
Hard Drive(s) are not Recognized
Check the following:
• Make sure the drive is not disabled in BIOS Setup.
• Make sure the drive is connected correctly and that is plugged into
the power supply.
• Make sure the drive is compatible.
• Make sure you have not exceeded the power budget for the
server.
• If using SCSI drives, verify that each SCSI ID number is unique on
