Your bios may be set to use Integrated Graphics. You need to set it to use Discrete Graphics. It might say "On Board" vs "PCI-E" for your GPU; select PCI-E.
Oh my god.. i did that and even turned on igpu and still nothing... there is less and less hope.. is it possible that this mobo is broken? Or my gpu? My pc Is only 1 month old. Can it be broken?
iGPU means your CPU's Integrated GPU or onboard GPU; this is not what you want. You want that set to AUTO (prefered) or PCI-E. Auto is nice because it will look for a PCI GPU; and if it can't find it, it will revert to iGPU.
Also, make sure that your graphics card is in the PCI slot closest to the CPU. Lastly, check to see if your card requires extra power connectors; if it does, make sure they are plugged in.
