Help for Graphics problem

ok, i bought a new gfx card (ati) plugged it in properly and i started my pc.

the monitor gives me nothing but the yellow light , i felt curious so i plugged the vga cable in the vga port for the built in GFX (and hey monitor works , yeah while the pci express card is installed)



so the problem is: even after plugging in the pci express card, the pci e card is kinda disabled and the built in is enabled.

i tried messing in the bios but eh no solution yet.


pls help


my mobo: Gigabyte 8I915ME
