I have the a toshiba L300 laptop, it all started when it would stop on a black screen with the curser on only, a friend told me to load another operating system onto the Vista, when I try to load the Xp disc on start up, it would not load, I went through the bios to load the cd first, it would not load, then all of a sudden, the laptop started up on its original vista programme and it let me do around 120 Microsoft updates, it was ok last night, then switched it on this morning to find I can only get the blue screen with an error message, my problem now is I cannot get by this stage, every time I switch it back on, I only have this blue screen, I have taken a photo of this error message but your site das it is to large to send to this reply, look forward to your thoughts on the above, Allan
