Hey guys! Ill try to make this as short and as sweet as i can for everyone. I recently just installed w7 32bit from XP, by using the upgrade version of w7, but im trying to make it so i can run w7 64bit version, so I purchased an OEM w7 64bit. My question is, is this even possible to do? Install the OEM w7 64bit over the upgraded 32bit? Ive read that i have to do a clean install, but when i boot from the OEM cd, it says "Windows is loading files..." and then it goes to the windows home screen and then just stops there. Nothing is being loaded, but i can still move my cursor freely. Any suggestions on what i should/could do to get w7 64bit up and running? Any replies would be greatly appreciated. Thanks!
