Q: Memory Issues This thread is locked from future replies

I have a Dell e510, 3.0g HT processor, Geforce 8400 video, ........I had to install Win 7 64 with just 2gigs of RAM.  After the install I added in another 2g of RAM.  It booted up and is working fine except its showing 4gigs with 3.25 usable.  I installed another gig of memory for a total of 5gig, (which my bios shows properly), but Win 7 wont boot with the extra gig. 

So the 2 questions are, why is it only showing 3.25 usable?  is that a vid card memory thing? 

and 2, why won't it take the other gig of memory when the bios recognizes it fine?
