3.3v was for very old AGP 1x boards. The IT7 is a pentium 4 board, so I can gurantee you that it is not a 3.3v board, and it has 4x agp, so there is no reason what so ever that the AIW 9800 should not work on that board. I would definatly not go back to that "tech", and not sure why you would trust him after he fried the original video card in the first place. It is quite possible they also damaged your motherboard, with whatever they did that fried your video card.
