READ the Motherboard's FAQ. The reason your fans do that is because when you first connect the power supply, part of the board turns on to monitor "Wake On" activity. In order to POWER UP the system, you need to connect the power button on front of the case to the propper place on the board. If that doesn't work, your board is probably grounded through a spare mounting post.

Probably some hardware is touching the case and shorting it out, if you then start the PC it will immediatly shut down.
Also check if all cables for the LEDs and power-on/rest buttons are connected properly.

My PC eats so much money that I'm in 'desperate' need of it to buy PC3500 RAM, help Svol with his OC project!
