I just installed another gig of ram (512 x 2) in my system. These 2 sticks are exactly the same as the other 2 that are in. But now something funny is happening. First of all, I crashed 3 times in a row trying to print a word document. And also, startup takes noticeable longer. It hangs a little when it detects the ram and the IDE devices... Should I just RMA it and get it over with?
