i jst switches off my pc , then after some hours, i turned it on but there is no display on monitor, but when i connects the monitor cable direct to onboard display it works fine though gamma is incorrect, what might be the problem with my card, an Nvidia foxconn card

The easiest and best way to see if there is a fault with the video card is to test that card in another computer, and correspondingly to get hold of a card that is known to work and put that in your computer. By doing this you can be sure where the actual fault lies.
