Switched dvi connection from discrete radeon to i3-2120 gpu "no signal

I tried connecting the dvi cable from the discrete radeon 6670 to the onboard igpu
i also changed gpu setting to onboard in bios. the computer turns on but the led monitor says no signal and goes to sleep. i switched the dvi cable back to the discrete card and the bios setting back to pci x16 and it works fine. why cant i get the hd2000 to work? Has anyone else had this problem? i dont want to use hd2000
as main gpu just wanted to see how videos play on youtube using hd2000.

Try changing your monitor cable from DVI to VGA. Sounds silly but it worked for me.

You may have to remove the Radeon 6670 to get the onboard to work. Detection of the dedicated card may disable it, regaurdless of the BIOS setting.
