System Troubleshooting 53
• Are the memory modules fully installed?
• Does your system have a computer virus? Run anti-virus
software.
• If there is a flickering display, unexpected restarts, or a locked
system, exit the application and start over. Although the
computers have a regulated and protected power supply, a
transient voltage in the power line or peripheral cable could
cause errors.
• Is the IDE cable from the hard drive properly connected? You
may want to check if the system will start from a floppy drive.
• Is the system overheating? Verify that the chassis fan is working.
• Is the alarm light on the 700R or 1400R computer on? The light
indicates one of three failures that may require service.
– The CPU fan is not operating at the correct speed.
– The CPU temperature is elevated beyond its rating.
– One of the power supply voltages is outside its specified
range.
If the alarm light remains on, the computer should be returned
for service.
Problems Running New Software
• Does the software have a hardware requirement that is not
present?
• Are you using an authorized copy of the software? Some copies
of software will not work without proper activation.
• Did the software install correctly? Reinstall the software.
• Are you following the software instructions? Refer to the vendor
user manual.
Problems With an Add-in Card
• Is the card installed and configured correctly? Check the jumper
and other configuration settings.
• Are cables incorrectly installed?
• Does the card use a dedicated interrupt? You may need to
reserve that interrupt in the CMOS setup PCI/PNP menu.
