Linux Live disc to see if the computer boots and everything works.
Maybe try booting up Linux Mint give it a go and let us know ...
I have a 15 year old laptop that I am trying to boot up but I have tried everything and it refuses to. It wont start in safe mode (i get a list of windows/driver...sys paths), it wont start in last good configuration, it wont start normally. I have tried booting from an XP Professional repair CD but it jut ignores it, even after changing boot priority in setup. This happened after I updated the graphics drivers.
I am out of ideas and thought I would try here before I throw it out the window. Any help would be greatly appreciated.
