Windows 7 stuck on CLASSPNP.SYS
I'm having trouble with my Windows 7 machine It was fine, until this morning, when, for no reason what so ever, it decided not to boot past the "Starting Windows" screen No hardware has been installed / removed.
I tried to boot into Safe mode, but it got stuck on classpnp.sys
I tried to do a recovery - by booting on to the windows 7 dvd... This did not work either.
Any ideas?
