hello all. question for you. my computer has Windows XP 32-bit, and i'm trying to do a clean install to Windows 7 64-bit. this is my processor. i'm assuming it can take the 64-bit version. i boot from the disc, press any key, and all the files load and whatnot. i see a screen that says "starting windows", and the logo appears. i figure that's a good sign. but...after that, i get stuck on a screen with nothing but some "desktop wallpaper" and my mouse. it just sits there. i can move my mouse around, but no installation options pop up. i bought the upgrade version of Windows 7, and i'm under the impression that you should be able to do a clean install using those discs. i stuck the 32-bit disc in my drive, and the install menu showed up no problem. but i want to install the 64-bit version. >_< i'm unsure of how to go about this. do any of you have any advice?
