I installed a Radeon 4870 in my Gateway DX 4200 but it doesnt want to stay put. The long part seems to go all the way in but short part I think can go in further but no matter far i push it wont go down further. So im guessing its far as it can go so now im on it right now but i got to keep the computer on its side because it will stay but the slight little move to set it right side up makes come loose a little and it wont work. I wont get close enough downward for me to screw it in to the back of the computer with those little screws. Newb I know but anytips this sucks. I wont to keep it stayed put for good.
