    My Computer Can't detect my new graphics card


    I purchased a new GPU Sapphire Dual X R9 270X 2GB DDR5 OC WITH BOOST
    My Graphics Card fan work fine but when I turn on my pc the monitor does not show anything.

    I had another graphics card before but needed to replace it so I dont know if this is the trouble.

    Anyone can help?

    Thanks in advance

    Do you have required power connections to it ?
    Tried another PCIx slot ?
    Monitor connected to the right place ?
    Can't be problem because of another GPU for BOOT at least, in the OS later on maybe, if it's different than old one.

    Yes I have the required power connections to it. I also tried another PCI slot. Also monitor to the right place. I am thinking that maybe the GPU is DOA because i ordered it through amazon.co.uk. I also know that this is not a problem with my motherboard as my old GPU works fine...

    Did you do a reset (optimized defaults, etc..) in the bios/uefi after putting in the new video card ? That's important, if the bios/uefi aren't set to detect the right video card, Windows won't either. Did you uninstall the old video card's driver's ? That's really important, especially if you went from nVidia based gpu to a AMD gpu. Did you install the current driver's for the new video card ? Not the driver's that are on the cd that came with it (they're alway's old driver's) ???
