•
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.
Note: 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.
