Avtrician. Including stripping out everything on the mobo I replaced the battery yesterday, and re-installed everything back onto the mobo today. There was a small improvement but it just freezes at 'Starting Windows.'
There appear to be so many different reasons. One is that Safe Mode rolls down list of files but most times they stop at classpnp.sys - no amount of waiting helps - a mass of replies on that too. I cannot get my Win 7 disc to play and although there is a plethora of 'answers' none seem to help. My hard drives are working OK. 'Windows Boot Manager' just says put the install disc in and use it to 'repair computer' - I wish.
