I have finished building my first pc and everything in it is working. The problem is trying to install windows 7 onto it. I install it then it goes to starting windows and a few minutes later the windows logo appears this stay for about 5 minutes then the text changes to "setup is updating registry" after 5 minutes of this it goes back to installing windows and is stuck on completing installation even though it has already done this any help would be appreciated in trying to solve this thanks
