I had something similar happen to me once. I actually took off the cooling block and the cpu but when I was cleaning the block it fell and landed on the motherboard taking out about four pins on my lga775 board. To my amazement I actually tryed to realingne the bad pins and they all broke off. I installed the the cpu back in the socket turned on the computer and it worked. I actually ran it like that for about 4 years without any problems, I never overclocked it though but it worked as good as it should. Im not sure how that happened but I guess I was lucky. either that or those missing pins didnt do much. hope that helps easy your pain.
