Windows 7 will NOT install 64-bit on my computer, only 32-bit!!

I just formatted my computer and after completion of my install of Windows 7 I noticed that it installed the 32-bit version, yet for the last year it has been running the 64-bit version!!

I have no idea why it won't let me install the 64-bit version, I even tried another fresh install of Windows 7 but I got the same result.

Thinking it was hardware, I ran the Windows Experience Index and then clicked "View details etc.." and it indeed did say that my system IS 64-bit capable!!!

What am I doing wrong?? Or what am I not doing in order to reach the 64-bit install threshold? Please help and thank you for reading and responding :) :)

I also have my ram and processor overclocked (running at 3.1 ghz)

Here is the log from 5 minutes ago on my lates WEI run!

The gaming graphics score is based on the primary graphics adapter. If this system has linked or multiple graphics adapters, some software applications may see additional performance benefits.
