When trying to power up from cold start all I get is a fast flashing light on the front. Pressing the front power button gets no results. Tested the power supply and all voltages are there except -5, however I see no -5 mentioned on the power supply label. Monitor of course has no screen display. Problem occured after vacuuming the inside. All connectors are seated good and nothing looks abnormal inside. Fans are not running.

vacuum cleaners produce static and you have likely blown something on the board. The static voltage inside you machine will have been different to that produced by the cleaner. But: Try this last hope. Pull out the main power supply lead from the wall socket and leave out for a full 24 hours.
I would suggest holding in the power button for at least five seconds to make sure that the computer is off and not stuck in hibernate or sleep. Then I would suggest replacing the power supply and see if that works.
The power supply was replaced and the problem is solved. Thanks Ray. I was testing the PS with the Thermaltake Dr. Power model which does not have atest for the 5Vsb. I tested the bad power supply with the newer Thermaltake Dr. Power II and the 5Bsb showed bad.
Is there a way to close a problem on this Q&A board?
