    Ok so i have pc which has an APU so i decided to add an gpu from my old pc since my motherboard has slot for it. After i added my gpu and connected it to my screen i turned on pc but it didnt detect my GPU.I can hear the fan but my GPU is not detected also i cant change screen resolution and i think my pc is now running on vga graphics or something like that.I am newbie when it comes to computers so any help would be appreciated.

    I am running Windows 7 ultimate 64 bit

    My motherboard is gigabyte f2a68hm-hd2

    So you have added a GPU , yes ?
    Does this GPU need extra power and if so have you a PSU with the correct power cables and indeed connected them ?
    You may well have to set the BIOS to use the GPU as default.

    Then have you actually plugged the monitor cable into the GPU ?

    I ask this cause the last machine I built up for my sons mate had onboard graphics as well. Within ten minutes off him getting his machine home he was on the phone all irate saying it was broken and I had built a dud ????
    Turned out he was only plugging the HDMI into the onboard graphics slot.

    I have a simular gigabyte board different number but the FM2 type..

    plug monitor into onboard graphics port, go into bios, i think its under peripherals menu, change primary video to pci-ex, and if the option for integrated graphics is there change that to disabled. save and exit the bios. shutdown the pc, plug monitor cable into the pci-ex card and turn on pc. Hopefully it will now work.

    Under primary video device i have 3 options ( IGD Video, NB PCIe Slot video and PCI Slot video) I set it to NB PCIe Slot Video and disabled integrated graphics but its still not detecting my GPU..

    If i remember the HD 4600 was just powered from the PCI-ex slot and no 6pin power was needed as long as the PSU was more than 350watts it should be ok. As mentioned you may need to go into the bios and change the Primary graphics from onboard to pci-ex and if that option to turn off the onboard gfx is there to turn that to off, then save/exit/reboot put monitor cable into the HD4600 vga/dvi/hdmi socket which one your monitor fits into.

    Gigabyte AMD boards are fussy for some reason, maybe because some use the hybrid crossfire feature, i could never get that feature to work!

    I know one combination works as my GB board was a pain at first.

    Depending on the A series cpu/apu you might find the HD4600 actually slower. I have an A6 series and the onboard is equiv to a R7 260 (rebadged HD9xxx series).

    I know some new boards can be fussy on the type of PCI-EX card fitted, not sure if it something to do with the revision of the pci-ex slot. The GByte site only lists CPU's/Ram the board can handle. The settings in the bios should be ok that you set - technically. More so as the option to disable the onboard gfx is not shown if no pci-ex card is fitted so the board must 'see' it but it refusing to allow it to actually be 'present' to the OS etc.

    The screenshot of the device manager screen, is that with the onboard gfx or the HD4600 ? I meant to say monitor plugged into the HD4600.

    If your monitor is plugged into the HD4600 and you are getting a display , then you will just need to download the HD4600 win7 x64 driver and install.

    Ok then it works :)

    So remember to go back into bios BEFORE removing the HD4600. or you wont get any onboard display. Then when you get a better card do the steps to turn off the onboard card, save exit bios, turn off pc, put new card in , turn on and away you go :)

    VGA is a standard driver that is installed so not to worry about that. The error maybe because the card is not compliant with the pci slot. It looks like the pc has detected the card ok, just that windows is being typical windows.

    When you get a better card the drivers should all work with that new card i always use the drivers that come with the new card, as sometimes the generic drivers on the AMD or Nvidia site tend to not always give better results.
