Let me preface this by saying that I'm I'm not very computer literate so any help needs to be worded simply like for a child..I have installed WIN 7 64 and it has developed a problem..It wont boot to the desk top. It will post and go to the starting Windows screen sometimes and stops there..It wont go to safe mode.Is there a way to make a boot disk to get it to start or any kind of a diagnostic disk that a dummy can do? I really need help...Thank you
