i built a system for my sister and can not get windows 7 to load at all. i have built and fixed many systems and i'm using the system i built for my sister right now. it runs anything i put into it but the windows 7. i have tried so many ways of making it work. first was just the full install and it would stop at installing updates, that was several times. then as an upgrade, with my vista i run on my other systems and same thing it freezes up. then i tried with windows wp but it was a 32 bit and would not let me upgrade with the 64 bit i wanted to install. my last is this xp professional 64 bit and still the same thing it stops at installing updates. i know it is not the system because it runs everything and i even do the windows 7 compatability check and get all green checks. so is it just a bad copy and what should i do can i get a replacement and where? i got it from new egg in may and have been fighting with it for so long now. please help if you can thank you.
