I just got a labtop from my brother in law that is having a problem booting up. Immediately on start up i get a message "Pri Master Hard Disk: S.M.A.R.T. Command failed" i press F1 to continue booting up anyway i get to the windows XP loading screen, then a half of a secomd of the blue screen of death and the whole proccess starts over again. I dont know what the exact problem is. Can anyone guess/tell me what i need to do or replace?
