8 gig of RAM is not considered by a 32 bit OS. The bluescreen when installation might be pointing to the sticks installed since its running currently on 32 bit. Yes, a 64 bit OS would recognize a 4 Gb and above of memory dependent of your motherboard specified maximum sticks allowed.
What Im attemping to do is load 64 bit on my second hard drive to create a dual boot, transfer files I need and then remove the old hard drive with the 32 bit windows.
You don't need to dual boot just to copy files from the old drive to the new hard drive with a 64 bit OS. Just remove the old drive and replace it with the new drive and then change boot priority to optical drive (with Win 7 disc 64 bit in place) and then follow the directions on screen. Prepare or Download all important drivers on USB or external drives first. Install the chipset or CD that came with your motherboard then Video card, Network, Sound. When everything is set, power down desktop and insert the old drive internally as it would now become your 2nd drive (data drive or backup) which you can transfer important data to your newly installed Win 7 64 bit hard drive.
