There is nothing wrong with your PC. I have 32 GB of RAM and the same thing happens to me. My Graphics card has 4gb on board and when my system starts up 4gb is shadowed by the system ram so 8gb is available to the video card. After I have started a virtual machine that runs Windows 10 (either 32 bit with 3gb Ram or 64 bit with 8gb) the memory is allocated to the VM PC's. After a certain time with say 2 or 3 machines running the video card ram is released back to the system. You are not loosing any memory the operating system is using it, otherwise what would be the point of having the memory installed if the OS did not use it. You need to do something to use more memory and then the memory will be used. I have just run the X3 demo and my card HD 7770 2gb grabbed 4gb of system ram to play with.
Edit I am talking about 2 different systems ........
