• 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.
