I have installed Windows 7 successfully (the only OS on a newly formatted machine) however each time I have set it up and turned it off . . . the OS will not start up again.
Sometimes it has the Windows writing at the bottom (but no image) and other times just a blank screen . . .
I have tried the system startup fixing thing a number of times, have tried a system restore, have pressed F8 (last good config & safe mode both have proved useless!)
The only option I had was a clean install.
The problem is, the same thing happened again!
