Here are five common-sense techniques and strategies to solve common computer hardware problems.
(1) Trial-and-error
Personal
computers are highly modular by design. The most powerful
trouble-shooting technique is to isolate the problem to a specific
component by trial-and-error. Swap compatible components and see if the
system still works. Try different peripherals on different machines
and see if the same problem occurs. Make one change at a time.
(2) "It's the cable, s-----."
More
than 70% of all computer problems are related to cabling and
connections. Ensure all cables are connected firmly. IDE and floppy
ribbon cables and power cables can often go loose. Ensure
microprocessor, memory modules, and adapters such as video card and
sound card are inserted correctly and didn't "pop-up" during
transportation.
(3) Don't be frustrated!
Don't
be afraid of computer problems. It is often the best opportunity to
learn. Trouble-shooting is part of the fun of owning a computer.
Imagine the satisfaction you could get by solving a problem yourself.
Of
course the fun could ran out quickly once you are frustrated and have
spent too much time on the same problem. If you feel frustrated, it's
time to leave it for a while and go back with some new ideas or call
someone who can help. Rule of thumb: You shouldn't spend more than
three hours on the same problem at one time.
(4) Take notes!
Take
notes of what you have done and all the error messages. You may need
to use them later. For instance, when you see an unusual blue screen
with an error message, copy the entire message onto a piece of paper.
In many situations, that message may point to the right direction in
getting the problem solved quickly.
(5) Take a look?
It's
OK to open a computer case and take a look inside. There is only 5V
and 12V DC voltage supplied to the components outside the power supply.
Those who have never seen the inside of a computer are often amazed by
how simple it looks. Of course, still always power down and unplug the power cord first.
