Do you have both the PCI-e and the PCI graphics card in at the same time? If so, that could be the problem because by default the main type of graphics card set in the bios is integrated, but if you installed a pci card before the pci-e, the main would be set to pci. The motheboard may not support disabling all the PCI-e graphics devices. Try looking into the BIOS and see if PCI is selected or PCI-e.

i went to bios and set it so the pci-e will start first but then neither video cards sent a signal to the monitor...so i had to clear cmos...now im back to the same problem...

Are you sure you plugged the PCI-e video card into the PCI-e slot? Is it secure?

 

[Rich88]

yes the card is in the pci-e slot and the fan is running

Is your PSU supplying enough power? Are you overclocking?
