Hi, I want to share how to knowing the specification of the computer without open the hardware.
Press "Start", type "Run" and open it (or you can open it with another approach: "Windows + R")
Type "dxdiag" and then new window will shop up
And there, you can see your computer specification, from computer name, OS, processor, memory, and you can move to the next page which display the specification of your VGA, and specification of your sound
