Whether the PC is 32 or 64 bit is defined by your OS, not your hardware ( except for some very very old CPUs that don't support 64bit OS ). 32/64 bit are just different types of OS ( generally, 64bit version of OS supports more RAM, and some new programs only run on a 64bit OS, while 32bit ones is more friendly to old programs that haven't received an update for years ). So, without an OS installed, your question is invalid.
