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).
