Hi, I've just purchased a second hand Compaq Presario C700 which is 2 years old. It only has 1gb of RAM. I did have a Dell Latitude D800 which had 2gb of RAM and I'd like to know if I can take the RAM from the D800 and put it into the C700 or whether the memory from the older (D800) would not be compatible. If not can anyone tell me where I can find good memory for the C700 and how much it should cost more or less? Thanks!
