Monitor wont work with new graphics card

[Guest]

Hi,
Well i have a Dell e520 and just yesterday i just purchased a xfx geforce 8600gt, now here is the problem when i slot it into my computer and connect my monitor nothing happens the monitor just dosen't kick in, what could possibly be causing this? i know that i have enough PSU, i've disabled my old integrated card and i've tryed plugging my monitor to my old card and new.

i think u most set the PCIe Video card as default or Primary video output in the BIOS option .
