Q: I press the power button on my Mac Pro - it takes 3 to 4 min before startup chime comes on - does anyone know cause or solution please?

I press the power button on my Mac Pro - it takes 3 to 4 min before the startup chime comes on. Once chime comes on the computer starts up and everything seems normal.

It never used to take this long - does anyone know cause or solution please?

Mac Pro, Mac OS X (10.6.8)

    Another theory is that the Power is unstable initially, and that it takes several minute for it to stablize and start the processors.

     

    If this were true, the fans would run at TOP speed until the processors "wake up". The running processors would then set the fans based on the temperature readings, and the fan noise would calm down to normal running levels.

    If this is still making you crazy you could take it to the Genius Bar in a big city, where they may have seen these machines before. An appointment for an evaluation is free, in warranty or out.
