• Check your system for a virus infection.
• 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.
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.
