is there a software used to find out a defected component in PC?

Answer 1

You might try downloading and installing and using a free program called "Belarc Advisor". It's available at the below link. Good luck.

Answer 2

There's an easier way than that, without installing anything.

Click the Start Button.
Select Control Panel.
Double Click "System"
Switch to the Hardware Tab.
Click the Device Manager Button.

Here, there is a list of every piece of hardware in your computer. If anything is X'd out, or has a yellow exclamation mark, there is a problem.

Another way, for a smaller amount of items:
Click the Start Button
Select "Run"
type dxdiag and click Ok.
look through the tabs, and check different diagnostics.
