The title pretty much explains it, i recently installed a new motherboard and installed all of the drivers. I don't understand why this is happening. Please help, thank you.

Are you sure that youre motherboard can support 8GB of ram? If it cant only the amount it can support will be usable. In this case its 3.9GB(4GB basically)
Would you mind stating your motherboard to verify the amount of RAM it can hold?
And also, What version of windows are you running? 32 Bit or 64?
If it is 32Bit it can only support upto 4GB of ram. (64 Bit will support more)

You are using Windows 32-bit. It will only support up to 4GB of RAM. You need to upgrade to a 64-bit system in order to use more.

You either just got over 4GB RAM so now you're noticing it, or your previous OS was an OEM and stuck with the old motherboard, making you recently install a 32-bit OS.

I have 2 sticks of 4gb ram, they are in the blue slots on my motherboard, do they have to be right next to eachother?

They are supposed to be spaced apart. Slots 1 and 3 should be occupied. You could also do 2 and 4.

Try each stick of RAM separately. One of them may be faulty. Since it is a new motherboard, one of the slots could be faulty also. Try different combinations, such as in slots 1+3, then 2+4, then one stick in all of the slots one after the other.
