any one got any idea's why two of my atx power supplys one used in the house and one in the car bolth worked fine one moment turned em off and then no longer turn on <happenened at diffrent times > i don't think it's computer related cause i can unplug bolth of them from the mothe boards and all i get is the soft buzz niose that occurs when you short somthing out i don't see any visibly damaged components so if any one has any idea's where to look to fix this it would be great

by the way bolth computers work just fine with diff psu's
