Maybe you could try connecting your monitor to the integrated graphics connector, accessing BIOS from there and changing it back?

I assumed that you've changed the video graphics adapter from your graphics card to the intergrated graphics in BIOS.

how to connect monitor to integrated grpahics connector??

At the back of your desktop PC you should have (usually) a VGA connector, simply connect your monitor to it.
Here's a picture that'll hopefully help to illustrate what I've just said:

From what I've understood, you've been using your graphics card and it will not work now that you've changed your BIOS to use the integrated graphics.
Connect to the integrated graphics and change the setting back, after doing so you'll be able to use your graphics card normally (no blank screen).
