I have a gateway gm5632e . I am trying to upgrade to 64bit and went ahead andmaxed out ram at 8gb. I didn't find any exact info on the motherboard so I got two 4gb sticks and a new video card.I installed it all and the computer beeped two regular beep and then two rapid multible beeps. So I imediantly new the computer wouldn't except 4gb sticks , so I removed them and reinstalled the factory ram. Then when I turned it back on it beeped again like before . So I removed the video card ,and still same . So I know its the ram causeing it . Why? Why will the original now not work?
