Is there a reason for going down to 32bit? It would be best to stay on 64 bit windows, for more application support and more RAM. 64 bit operating systems can run both 32 and 64 bit programs, while 32-bit os can only run 32bit programs. Also, 32bit has a 3.5GB ram limit. 64-bit, on the other hand, supports up to 128GBs of ram. Did your laptop come with a cd to install drivers?
