You are correct. I do not remove the mobo if the system boots as it should. These corrective measures are for a serious problem with someon's computer. Sometimes I find all sorts of stuff that is wrong and wonder how the system ever worked period. I have ran across the hs/fan attached to the cpu, the fan not plugged into the proper plug, no thermal compound between the cpu and hs, just for starters. Good thing most of these were Intel systems. AMD's would not do anything but burn out the cpu as soon as they put the power on. I have seen some of these also, the last one I found had the corner actually burned off the cpu. I just believe one should come prepared to handle most any problem, look for the worst serenio, than if it is not as bad as good be you are better off.
