Pavilion Desktop 570-p030 will not power up.

[navyguybob]

No startup.  Took the cover off to observe.   Unplugged the power cable, then plugged back in.  The green light comes on.  Hit start.  CPU Fan spun briefly, then no green light or anything else.   Power supply suspected. 

How can I confirm ?
