Hey guys, Just 3 days ago I formatted my PC . Now , when I close a window , suppose "My Computer" or any other window , it closes after taking 1-1.2 seconds. It is not closing in an instant of the click. It also happens when I right click on my desktop to refresh , the right-click menu opens taking 1-1.2 seconds , as it it is opening up slowly. And also other windows and apps has gotten slow.
My spec is :
CPU : Core i7 4th gen 4771
RAM : 16 GB DDR 3
GPU : ASUS GTX 760.
WINDOWS 7 x64

Can anyone help ?

Thanks in advance.
