wait u unplug it and wonder why the fans still spin when u press the power button? its called residual power. every computer in the world does that to some degree.
A 2003 study found that some spurious computer crashes and general reliability issues, ranging from screen image distortions to I/O read/write errors, can be attributed not to software or peripheral hardware but to aging capacitors on PC motherboards. Ultimately this was shown to be the result of a faulty electrolyte formulation.
maybe the new psu isnt powerful enouth for your computer either. Try the psu in a computer with pretty much the same specs as yours if you can. If that system doesnt power up, its the psu. If it works fine, then your motherboard will more then likely need replacing.
i bet its the power supply because the new power supplies with a higher W have a huge transistor capacity and until it gets discharged it may do that. be usually there has to be a failsafe against that in the PS
that looks like the powersupply. try relacing it. don't use the split cables for pc and monitor. Check the 12v connector is in. Clear the CMOS. REmove the battery and put the jumpers in place to clear it. Leave for about 20 minutes (trust me on that). if the problem persists, remove all expansion cards and disk drives and try it then. If all else fails, its likley that the board is faulty or there is a short.
Well it would be easier to figure out if the computers was in front of me, but I have some ideas that may be relevant to the situation. The core fan may be really dusty which can make it act up like that, plus you should also try checking the power supply fan, they can burn out if you don't clean them enough and that may be your problem. I'll try to brainstorm some other ideas, so get back to me and ttyl! :o)
Seems that the psu is turning itself on, thing is must be only the 5v/3.3v as the 12v would only last less then a second, as there is some power left in you psu's capacitors. Looked like a cheap psu, would not surprise me.

Does it still work? If it works and is unplugged, then the capacitors still have electricity in them, which is normal, and is being discharged.

thats not normal

how does it do that? there must be a big capacitor inside the psu or something for it to do that so many times.

@Hrothgar520 the vga or dvi cabel from your monitor can give it a little bit power to spin like that
