I have been having this problem with my graphics card where whenever I play games the graphics card will start making this rattling/vibrating/buzzing sound in my pc. I have opened the case to help locate the problem, and found if I hold the card tightly with my hand or slightly push the card up the noise seems to stop. I believe the card is just vibrating metal on metal, but I would really like to find a way to get it to stop due to the noise being incredibly bad sounding. Thanks.
