User's Guide Troubleshooting
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.
This will void 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.
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.
Don't over complicate things. The less you have to deal with then the easier the source of the problem may be found;
Example - if your computer has many devices plugged into its ports, and a number of programs running, then it will be
difficult to determine the cause of a problem. Try disconnecting all of the devices and restarting the computer with all the
peripheral devices unplugged. A process of elimination (adding and removing devices and restarting where necessary)
will often find the source of a problem, although this may be time consuming.
