Upgrading and Adding New Hardware/Software
• Do not be tempted to make changes to your Windows Registry unless you are very sure of what you
are doing, otherwise you will risk severely damaging your system.
• Don’t open your computer or undertake any repair or upgrade work if you are not comfortable with
what you are doing.
• Read the documentation. We can assume, since you are reading this that you are looking at the com-
puter’s manual, but what about any new peripheral devices you have just purchased? Many problems
are caused by the installation of new hardware and/or software. Always refer to the documentation of
any new hardware and/or software, and pay particular attention to files entitled “READ ME” or
“READ ME FIRST”.
• When installing a new device always make sure the device is powered on, and in many cases you will
need to restart the computer. Always check that all the cables are correctly connected.
• Make sure you have installed the drivers for any new hardware you have installed (latest driver files
are usually available to download from vendor’s websites).
• Thoroughly check any recent changes you made to your system as these changes may affect one or
more system components, or software programs. If possible, go back and undo the change you just
made and see if the problem still occurs.
