Thanx to all of you but now problem has changed. I have recently changed my mainboard
though i broght the same brand(Mercury 845 GL) but the Company has changed the board a bit. And now the rage card is not fitting on the board. Actually this card was first in my intel 850 board. I had some problem with that board and i changed the board. I got well fitted in my last mercury board( Intel chipset). But Now when i bought this new mercury board(intel chipset) it is not getting in any of the slots not even in the CNR. Though the model number is same.
