Do you get the chime?
Do you get the gray screen?
Do you get the dark gray Apple?
Do you get the gear?
Does the gear spin?
Does the gear spin for the usual amount of time?Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

No chime, no screen, no dark grey screen. I hear what sounds/feels like the two fans going full power but nothing that sounds like HDD access. I don't know what the normal amount of time would be but it goes for a while - i haven't timed it, I interrupt it because i'm afraid it's damaging my computer further.

If you have no chime you have a very fundamental problem.
The chime is generated in software after millions of instructions have been exectuted and the first part of the power on self test has passed.
The fans are set to high by Hardware at power on to avoid damage if the software crashes. They are re-set based on measured temperatures when the software runs or continues to run.
To make progress, remove everything that could be dragging down power including the graphics card and all drives. If no joy, back off to one set of DIMMs. You are looking for the chime -- without that, you get nowhere.Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

I removed the graphics card - all the drives and but one set of DIMM's with no difference. Fans still stay on full power until I cut power. It does show the white power light on the front though.
What else could I try?
