I have a touchsmart 520 pc and i just installed windows 7 and i just checked my system properties and im 32 bit. but i know for a fact that my type of computer never had a 32 bit. also i went to the manufacturer website to install my drivers and no 32 bit popped up. so wtf do i do now? lol i cant even connect to the internet its a messed up situation. if anyone knows what to do so i can get my comp back to 64 bit that would be great. and if its not possible to take it back up to 64 bit, is there anyway i can possibly run on 32 bit, and whats the difference between the two.
