How to disable on board video card on M4A88T-M/USB3 / Not working asus radeon hd 7790

So i bought the asus 7790. Installed it corectly and when i turn on my pc on the screen it says:
"No Signal"

I've heard that for a not integrated graphic card to work you need to disable the onboard viedo card. I've tried doing that still nothing happens.

Any suggestions on what i could do?

Please reply.

    Do your monitor says''check signal cable''when you pug the vga port to the appropiate port of your graphic card?
  2. Depending on you bios, you may have an option to choose which is your primary display adapter. I would go into to bios and make sure that your new gpu is being recognized, if its not then that is your first problem.

    If you monitor has multiple inputs, make sure you have the right source chosen on the monitor and obviously check your cable connections to make sure they are seated correctly.
  3. check again if you gave power give everything a squeeze to be sure.
    even with integrated graphics cards this shouldn't be happening.if you want to disable.if your graphic card fans power on and no signal there is a possibility that your power supply cant power the card or that your graphics card is defective.
    tell us what power supply you have and your specs.
