Good news. The Mobo Biostar sent out arrived when they said it would. It was tested by them, the colck was set and the date was correct. It even had the most current bios. However once installed and with the new memory the Kingston PC 2700 or the Ultra PC 3200 in, the same thing happened all over again. The board would only post with the old Samsung PC 2100 memory. After a couple of trys swapping between the different memories all of a sudden the PC 2100 would no longer post and was giving the same "CPU changed" warning message and would not reboot after bios reconfig. Well, upon closer inspection of the memory and the socket I noticed that I had crushed an aphid, yes an aphid in the first slot. Last week we had a warm spell and these critters end up everywhere. What a mess, after cleaning the connector and the memory, the system was back to normal with the PC 2100 memory. This made me look real close at this new memory and in paticular the contacts. What I found was a very thin coating of what ever it is they coat these boards with over several of the contacts. Both the Kingston and the Ultra had this coating on the contacts. I used an eraser from an ink pen to clean the contacts and the rest is history. The contacts had what looked to be good markings from the contacts in the connector but were insulated by the coating. What a pain. The PC is up and running fine.
