If you are determined to get 64 bit install, then shrink your 32 bit installation in Disk Management and format a test partition to continue trying to install 64 bit from booted DVD.
When the install bluescreened, did you try entering Safe Mode by tapping F8 during reboot?
Also, did you try booting into the Windows 7 DVD Repair console to select Startup Repair and run it repeatedly to try to get Windows 7 started? Did it find an OS to repair when doing this?

SIW2, where would he find these logs and when? He bluescreens out at booted 64 bit clean install finish. Only succeeded at 32 bit in-place.
