Troubleshooting
FAQ
This
section of the manual is designed to help you with problems that
you may encounter with your personal computer. To efficiently troubleshoot
your system, treat each problem individually. This is to ensure
an accurate diagnosis of the problem in case a problem has multiple
causes.
Some
of the most common things to check when you encounter problems while
using your system are listed below.
-
The power switch of each peripheral device is turned on.
- All
cables and power cords are tightly connected.
- The
electrical outlet to which your peripheral devices are connected
is working. Test the outlet by plugging in a lamp or other electrical
device.
- The
monitor is turned on.
- The
display brightness and contrast controls are adjusted properly.
- All
add-in boards in the expansion slots are seated securely.
- Any
add-in board you have installed is designed for your system and
is set up correctly.
Monitor/Display
If
the display screen remains dark after the system is turned on:
-
Make sure that the monitor's power switch is on.
- Check
that one end of the monitor's power cord is properly attached
to the monitor and the other end is plugged into a working AC
outlet. If necessary, try another outlet
- Check
that the video input cable is properly attached to the monitor
and the system's display adapter.
- Adjust
the brightness of the display by turning the monitor's brightness
control knob.
The
picture seems to be constantly moving.
-
The monitor has lost its vertical sync. Adjust the monitor's vertical
sync.
- Move
away any objects, such as another monitor or fan, that may be
creating a magnetic field around the display.
- Make
sure your video card's output frequencies are supported by this
monitor
The
screen seems to be constantly wavering.
-
If the monitor is close to another monitor, the adjacent monitor
may need to be turned off. Fluorescent lights adjacent to the
monitor may also cause screen wavering.
Power
Supply
When
the computer is turned on, nothing happens.
-
Check that one end of the AC power cord is plugged into a live
outlet and the other end properly plugged into the back of the
system.
- Make
sure that the voltage selection switch on the back panel is set
for the correct type of voltage you are using.
- The
power cord may have a "short" or "open". Inspect
the cord and install a new one if necessary.
Floppy
Drive
The
computer cannot access the floppy drive.
-
The floppy diskette may not be formatted. Format the diskette
and try again.
- The
diskette may be write-protected. Use a diskette that is not write-protected.
- You
may be writing to the wrong drive. Check the path statement to
make sure you are writing to the targeted drive.
- There
is not enough space left on the diskette. Use another diskette
with adequate storage space.
Hard
disk failure
-
Make sure the correct drive type for the hard disk drive has been
entered in the BIOS.
- If
the system is configured with two hard drives, make sure the bootable
(first) hard drive is configured as Master and the second hard
drive is configured as Slave. The master hard drive must have
an active/bootable partition.
Excessively
long formatting period
-
If your hard drive takes an excessively long period of time to
format, it is likely a cable connection problem. However; if your
hard drive has a large capacity, it will take a longer time to
format.
Parallel
Port
The
parallel printer doesn't respond when you try to print.
-
Make sure that your printer is turned on and that the printer
is on-line.
- Make
sure your software is configured for the right type of printer
attached,
- Verify
that the onboard LPT ports I/O address and IRQ settings are configured
correctly.
- Verify
that the attached device works by attaching it to a parallel port
that is working and configured correctly. If it works, the printer
can be assumed to be in good condition. If the printer remains
inoperative, replace the printer cable and try again.
Serial
Port
The
serial device (modem, printer) doesn't output anything or is outputting
garbled characters.
-
Make sure that the serial device's power is turned on and that
the device is on-line.
- Verify
that the device is plugged into the correct serial port on the
rear of the computer.
- Verify
that the attached serial device works by attaching it to a serial
port that is working and configured correctly. If the serial device
does not work, either the cable or the serial device has a problem.
If the serial device works, the problem may be due to the onboard
I/O or the address setting.
- Make
sure the COM settings and I/O address are configured correctly
Keyboard
Nothing
happens when a key on the keyboard was pressed.
-
Make sure the keyboard is properly connected.
- Make
sure there are no objects resting on the keyboard and that no
keys are pressed during the booting process.
Mainboard
-
Make sure the add-in card is seated securely in the expansion
slot. If the add-in card is loose, power off the system, re-install
the card and power up the system.
- Check
the jumper settings to ensure that the jumpers are properly set.
- Verify
that all memory modules are seated securely into the memory sockets.
- Make
sure the memory modules are in the correct locations.
- If
the board fails to function, place the board on a flat surface
and seat all socketed components. Gently press each component
into the socket.
- If
you made changes to the BIOS settings, re-enter setup and load
the BIOS defaults.
