Computer Hardware Trouble shooting...

If you have something wrong about your computer, just try following strategies first. These are the basic and simple things you can.

(1) Check the cables

More than 70% of all computer problems are related to cabling and connections. Make sure that all cables are connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Check whether that microprocessor, memory modules, and adapters such as video card and sound card are inserted correctly and didn't "pop-up" during transportation.

(2) Trial-and-error

One of the most powerful trouble-shooting techniques 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.

(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. .

(4) Be aware of what you do.

Don't do what ever you think. Just come up with ideas by thinking. think logically. Take notes or try to remember what you did and the corresponding response from the PC. This 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.
