I bought an assembled PC month ago. It worked with no problem but i was in a crappy case with no cooling. So i bought a old antec case with to fan and a fan controller. So I checked the fan controller and it was working but thecrapy case had no place for fan. So I decided to unmount my PC and rebuild it in the Antec case. Beside the two fan and the fan controler (who already worked with my PC). I changed nothing to the configuration. At first it would bot at all, but I realised I let a motherboard stand off in the wronf place, so I took it off. Now when I boot the fan spinnning and a few hardware noise but nothing else happen. The screen say's no signal and normally my motherboard should beep once to signal everything is wrking and that dosn't happen.

Ok guy's call me stupid. I just realised I forgot the 4 pin power near the cpu wasn't plugged in. I relieved that it is working again.
