    Are you using integrated graphics or a discreet video card? First of all make sure everything is connected. Make sure the DVI or VGA cable is plugged in.

    If you are using a discreet video card pull out the card and see if you get any video out put. You should automatically get video becuase the BIOS will automatically switch to onboard video. If you get video feed go into the BIOS and enable the PCI-e slot. Turn off the computer and put in the video card and see what happens.

    If you are using onboard video then it might be a problem with your CPU.
  2. You haven't give enough information.

    What are the specs of the pc?

    What cpu?

    What graphics card?

    What power supply?

    Have you tried another power supply, graphics card or monitor?

    First thing you need to do is to put motherboard speaker if you had one. Then remove your Graphics card then plug it back but don't screw it then try it up. Cheers!! :sol:
