Finally built my computer (can't believe nothing exploded... seriously), but I go into my computer properties and it says only 3.96 GB of ram is usable. Yes, it detects 8 GB of ram so I must have put the sticks in the right way and yes I am running windows 7 64-bit so please help

There's a number of revisions of that mobo - do know which one it is - there's 1.0, 1.1, 1.2, rev 3, rev 4 (also all show BIOS revisions as notaded to be Fx (where the X equals something else) (see here for Revision 4 mobo)

you have both RAM sticks in the same colored slots ? Ideally 1 and 3 ?
Have you tried with just one RAM stick? , and then just the other stick?

I had the same problem.
I think that the shortcut to fixing this problem is to reduce the speed of the RAM manually by one speed level in the BIOS. Maybe Asus's RAM's auto speed check does not work properly!!!
( As you know to get into the BIOS on an ASUS you press the delete key or the F2 key when the message appears on the screen when you are loading up the computer (ie booting the computer). I write this to help others that don't understand how to get into the BIOS).
In case this does not work then the following is what I did to fix it:
I pressed the MeMOK! button on my Asus M5A97 R2.0 motherboard (It is near the RAM - see the manual for the motherboard) (and maybe I pressed the BIOS Flashback button briefly - I can't remember if I did this second button or not. If I did then I did it afterwards.) I found that the auto speed of the RAM was changed to 1333Mhz instead of 1600MHz that I definitely remember it was originally in the BIOS. I can't remember what speed the RAM was on its box when I bought it. I don't want to take it out now that I have got it working. Sorry.
I now have the full 8GB working properly without the 3.9GB useable message.
