I've tried using just the 128 - same problem. The 128 is a good stick, works in another machine. The original 32 was working fine before I took it out and put it back in. I have checked that it is seated properly and the bios recognizes it.
Right now I am more concerned about getting it to boot up, regardless of the amount of RAM. It seems to me that if I put it back to original (32 stick, nothing else changed) that it should operate as it did before. It doesn't.
Thanks, but any other suggestions?
