Oh wait, 1st and second GPU are fine, the third one is now the problem.
When i remove it everything works........

Too late to rma?

I have a 3 years warranty, but can i return it after i ruined the bios?
And the switch is doing nothing.....

Reflashing the BIOS is a valid troubleshooting step. If it still isn't working chances are that the device shipped from the manufacturer in a defective state. Unless you've had a major breakthrough, claiming the warranty might be your best bet.
