Okay, just figured out that I can remove the fan from the a30 to get to the screw. Tightened it a bit, not too much. Hasn't effected temps at all though. Gonna make sure I didn't put on too much paste later, maybe that's it.
Btw, when I took out a ram stick(Corsair vengeans 1600 ddr3) the system wouldn't boot, just gave me "dvi no video out). But if I put the single stick in the other slot, it would boot. Same with the other stick. Is it possible the ram slot itself is bad? Because both 8gb ram sticks work depending on what slot they're in. Not much I can do, as the ram's not worth RMA'ing to newegg as it was only ten bucks or so anyway.
