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 as this may violate the terms of your
warranty.
• Read the documentation. We can assume, since you are reading this that you are looking at the computer’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.
