My laptop keeps crashing, in any situation, usually if its just on desktop. Then a blue screen comes up saying something about Kernel Data Error and loads of numbers. Then when it restarts the desktop comes up with a message saying there was a serious hardrive error. and most of my programmes then fail and error reports are sent. I've checked for viruses and i do the xp update things, i've no idea what it is or what to do. Is my hardrive dying??
