The computer boots up fine, but when I look in computer properties it is only recognising 2GB of RAM. I have Windows 7 64-bit installed. The 2 RAM sticks are installed in the first 2 slots on the mother board, as instructed in the manual, and where I removed the original 2 from. Motherboard - Gigabyte GA-MA770-DS3 Anybody able to help me with this one?
