1. the new memory card has to be a match to the existing memory card.
2. the new cards must be inserted in the correct slots.
3. after installing two cards in the correct slots, do a repair install of the XP operating system. This will configure the new hardware. See THIS forum, fourth post from the top, for directions to do the REPAIR install.
4. If you are sure that the matching memory is inserted in the correct slots, and you have done the repair install:
If the same problem occurs again, as described above, you have a DEFECTIVE motherboard.
