Post your exact make and model pc and we`ll help you along. :)

You do know you need a 64 bit capable cpu to run 64 bit, correct ?
I already know. Processor is a Intel Pentium G630 2.7Ghz dual core, 4GB RAM (3.3GB usable), nVidia GT220 (not that quite of a beast, but is powerful enough to run most games at minimal settings.), Windows 7 Ultimate 32 bit (going to 64 bit soon ). I checked it, and it said it IS 64 bit capable.

EDIT: This PC was purchased back in 2008. It has gone through NUMEROUS upgrades since. If I'm not mistaken, original specs were: Intel E2140 1.6Ghz dual, Intel integrated graphics chip (GMA 450 if i'm not mistaken.), 512MB DDR2 RAM, Windows Vista Home basic 32 bit. HP set...
