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?
