My PC refuses to boot up - the horizontal loading bar appears and the green dots / bars move across it but then freeze after a while. It used to be that I just restarted the machine a few times and it would start eventually start but tonight it just freezes everytime. start-up repair does not fix the problem and the extended details screen says unhelpfully - "unspecified changes to the system configuration might have caused the problem" I have not knowingly altered the config. does anyone have any idea on how to get the thing going again? and if I can get it going again how do I stop it happening again?
I hadn't done this and it has worked - the PC still seems slow though and the appearance has changed - task bar is that horrible grey colour you get in safe mode . But it's working which is the main thing so thank you for reminding me about F8. Dare I switch it off again though.......gulp!!!
