Is it possible for your computer to lose RAM? I shut it down, disconnected everything and moved it to a new location. At first when I tried to start it I couldn't; one of the messages I got was that the memory has decreased or something. It started the second time, but now it's showing about 256 MB, and I have 512 MB. Did I disconnect one of my RAM chips when I was moving my computer? If so, where do I find the RAM chips to reconnect it?
