Strange about it is that when it happens, farther turning it off and on 
does not work. I have to come to the computer next day, then it would 
sometime work no matter how many time I turn it off and on. A heating 
problem perhaps, requiring hours to cool? Or a charge accumulation 
somewhere requiring several hours to dissipate? I've never had this 
problem before.

Two years back it once acted like this but just for one occasion. Then 
never happened till some 10 days back and this time it has kind of 
stayed like that.
