I have been running win XP for 3 years,loved the stability(finally).Added Samsung laser printer 1 year ago.Worked prfect for 8 months,then every time you would try to print,it would reboot computer.Re-installed winXp and now it just shuts windows down!I added no new hardware or software around the time the problem started and have no clue on this.I have good,not great computer experiance,but this is beyond everyone I have spoken to.Please help me....Gary
