Computer does not turn on immediately

I have a Dfi lanparty mobo, AMD FX 60 processor, Geforce 7800 GTX 512 card, 600w psu, and recently whenever i push the power button the computer does not turn on immediately. It just sits there for anywhere from 10-40 seconds until fans start going and lights start blinking. I have tried messing with the power button itself to see if something came loose but nothing is wrong with the power button because if i want to press it to turn the power off everthing works fine! Everything works perfectly once its on, but its kind of annoying pressing a power button and having nothing happen.

 

Have you tried restoring your motherboard to factory settings?
Which power supply do you use?

 

I havent tried restoring my mobo to factory settings. never mind i thought it was 600 watt or so but its actually Antec TRUEPOWERII TPII-550 ATX12V 550W Power Supply - Retail

 

Hmm, which DFI Lanparty board is it?

 

i belive its a LANPARTY UT nF4 SLI-DR

You can try fiddling around with which slots stuff is in, but if no luck, you'll just have to be patient.
