my laptop keeps turning off by itself. and when i turn it back on, it sometimes turns off again, and when it does turn on again, it comes up with "errors occured due to hardware or software change" and it lets me turn on safe mode or start normally. but ive not changed a thing.

and just there, i turned it back on again, and it didnt come up with the error message, it just did the normal thing, but my fan turned on, full speed, for about 2 minutes.

is this problem because of overheating, or what, i thought it was, because the fans turned on, but the error message doesnt fit in at all.
