    What causes a PC to be 32 vs. 64 Bit?


    Is it the CPU, the Motherboard the O/S or what?

    If the CPU is 32 bit then the computer will be 32 bit, no matter what.
    If the CPU is 64 bit then the O/S will determine whether the computer is 32 or 64 bit.
    You can install a 32 bit operating system on a computer with a 64 bit CPU.
