okay, so i think i found the source of the sound which would be my fans, one of them, either the one on the back or the one on the side, but i've got a new question, the guard on the back of my computer doesnt match up with the connections, it runs at a slant, and i looked at the back of the computer to view the screw depth and the side that doesnt match up seems to be screwed in more than the others, can i unscrew the mother board a little bit on one screw to get the connections to align without messing up the computer, and one of my video hookups doesnt work, the one located on the motherboard, im not sure if the hdmi works as it is seated under it
