Listed on my computer when I go to properties, it says that only 6.98 GB of my 16.0 GB RAM is usable, does anybody know why this is?

I checked my bios and it listed that I had 16 GB RAM, so I'm kind of confused. The RAM I have is the Corsair Vengeance DDR3 1866 MHz 4x4GB.

Here is my Physical Memory in task manager, it says the total RAM I have is 7148 MB which equates to 6.98 GB RAM.

In conclusion, my system is not using the RAM available in my computer and I need help to fix this!

There will always be a difference, that reflects the amount of memory reserved by the system for certain things (like the GPU, as Trademan1 points out). It's all being used, it's just the OS maps certain things out to memory and reserves addresses ahead of time to avoid conflicts and crashes.
