The display is blank when I turn my PC on:
The monitor’s power indicator light is not lit.
• Check that the system unit is turned on and that the power light is lit.
NB If not, refer to ‘My computer won ’t turn on’ above.
• If the PC power light is lit, but the monitor is not, try turning the monitor off and back on
again.
NB If the monitor ’s power indicator then flashes on and off, then refer to ‘If the monitor’s
power light is lit’ below.
• Check the power cable is securely connecting the monitor to the mains socket and the
monitor signal cable is securely plugged into the PC.
• Unplug the system unit ’s power cable and plug it directly into the monitor.
NB If the monitor ’s power indicator lights up, then replace the monitor power cable.
If the monitor ’s power indicator still does not light up, then there is probably some other
problem with the monitor.
If the monitors power light is lit.
• Sit tight and wait for a moment.
NB When a monitor is turned on, it can take a minute or so before the display appears.
• Check that the brightness and other controls are correctly set. Try adjusting them to the
minimum and maximum settings allowed.
• Check that the system unit is turned on as well as the monitor.
• Double-check that the signal cable connecting the monitor to the system unit is properly
connected.
An "out of range" error message appears when powering on for the first time
in Windows XP:
• Restart the PC.
• As it starts, rapidly and repeatedly press the (F8) key or (F5) key to display the advanced
options menu.
• Select the option "Enable VGA Mode". Press ‘enter’.
• When you see ‘select operating System to start’, press ‘enter’
NB You should only have Windows XP listed there.

• Click on the ‘yes’ button after the "windows will try to adjust your screen resolution"
message appears and then click ‘yes’ again
My computer just beeps at me when I turn it on:
If the system unit comes on, but beeps at you continuously:
• Check if any keys on the keyboard are depressed
• In case of spillage, leave the keyboard to dry out overnight and try again the next day.
• Unplug any optional peripherals (if connected), such as printers, scanners etc.
• Unplug the Keyboard and Mouse from the PS/2 ports and shut down and restart the
machine.
NB If the beeping stops it would appear to be either a faulty keyboard or Mouse. You might try
a friend’s keyboard and mouse on your machine as a check.
I get an error message on the screen when I turn my computer on:
‘Disk boot failure’ or ‘Invalid system disk’
• Remove any floppy disks and CD-ROMs from the drives and press ‘Enter’
or
• If this doesn’t work, please seek advice from Technical Support to check the settings on
your computer.
‘CMOS Battery state low’
• Replace the CMOS battery which provides the power for the PC to maintain a small store of
vital information including the date and time.
Keyboard not detected or Mouse not detected
• Check that the mouse and the keyboard are plugged into the correct sockets at the back of
the PC.
or
• Check if they work on a friend’s computer.
The Windows logo stays on the screen and nothing else happens.
or
The PC has started but the keyboard and/or Mouse don’t work.
• Check that the mouse and keyboard cables are in the correct sockets. If not, switch off the
PC, swap the cables and switch back on.
My system won ’t let me copy a file onto a floppy disk.
• Ensure the floppy disk is formatted, not full and not write-protected.
I left my PC unattended for a few minutes and now the screen is blank.
• Move the mouse or press a key to bring back the screen, as the power management system
has put the PC in standby mode.
Which are the ‘back slash ’and ‘forward slash ’keys?
• The back slash key ‘\’ is next to the ‘Z ’key.
• The forward slash ‘/’ is on the same key as the ‘?’
When I press the ‘£’key I get the ‘#’ symbol or when I press ‘@’ I get ‘"’
• Use the ‘Regional Settings ’option in ‘Control Panel ’to select the English/British keyboard’
to change from the US settings as above.
