Here's the deal - After proper shut down to unplug computer to protect from lightning storm it now will not boot up. Historically it has done this in the past and after allowing to sit for a day or two it starts right up. There really has been no consistency with this - only that it has never done it when just shut down - only when it has been shut down and sits unplugged from the wall. If anyone could please help. I am far from a computer genius bust can usually trouble shoot on my own and have had no luck.
