I'm having some trouble with my sapphire atlantis 9500 128. When trying to boot with the power cord to the video card installed, there is no reaction. The cpu fan spins half a revolkution but then no more reaction. Booting with the power cord uninstalled works fine, but then I get an error message stating that the power cord is uninstalled. Don't think that this is psu related as my psu is 350W. The motherboard is an asus a7v-e with duron 1300 and 512mb of ram.
