Agreed. I would tend to go with the crappy power supply theory. There 
are so many of them these days that have been showing their true colors 
thanks to newer, more power hungry tech. Because of the relatively low 
cost of power supplies these days, I tend to find it easier to replace 
the crappy power supply than test the entire thing and fix it. 
Occasionally, I will solder a fan in though.
