Of course you cannot upgrade from 32 bit to 64 bit completely different OS you need to format and clean installation if you want x64. And also no point of installing x64 if you have less than 4GB of ram.
It says i have a 32-bit OS but when i go to my computer and check it says 64-bit and the Windows 7 CD i have is Windows 7 Ultimate x64. So i dont know why they say i have 32-bit also i have 8GB of ram.
Don't know what's happening could you have labelled the dvds wrong anyway still think you would be far better formatting and do a clean installation.
I agree with Urie - You should do a format and clean install, it sounds like your system is corrupt! Much easier and quicker to complete a fresh install now!
Hey Thanks I just said forget it and just download a new Windows 7 with SP1 and did a Fresh Install thanks for all the help. I just uploaded all my important stuff to Mega.co.nz or Mediafire.com
