  1. Your PC should be a 64 bit system...

    Have you formatted your HDD completely? You can't install windows 64 bit over windows 32 bit, you have to wipe your HDD and install from scratch.

  5. This may be an issue with windows not reading your system details properly...try updating your BIOS to the newest available version, and make sure you get the windows 7 compatible version. That should give us some insight. Update your BIOS and tell me if you still cannot install win7 64 bit.

  9. How much room is on your HDD? How much space is available?
