Monitor wont startup after i plug my graphics card into the board and connect my monitor to my onboard graphics card!

Help!
I bought a new graphics card gtx 750ti now my computer specs are:

Board- gigabyte b75m-d3h
Processor- core i3 3220 3.3 ghz
Ram- 4gb
Graphics card-gtx 750ti
Smps- intex classic 450watt

Now for the problem
When i plug my graphics card into the board and connect my VGA to onboard graphics slot(yup onboard graphics) my monitor wont startup
But as soon as i remove the card from the board the monitor starts up
Is it the smps or something else?

Note: My monitor has vga slot but my card has dvi slots that's why i didn't connect my monitor to my graphics card

u need to change the display setting from bios as pcie and then connect it to the nvidia port, and not ur onboard port...
currently ur display is set to onboard gpu, hence it cannot give u display from dedicated gpu...

So it is not the psu that is causing problems?

Monitor does not display anything at all
It is completely black but when i remove my graphics card then it works
Is it the psu or onboard graphics get disabled when graphics card is connected?

now getting to the issue...here is wat u need to do...
attach the nvidia card but boot ur system with the onboard gpu where u get a display...
next...get into bios and change the display to pcie setting and reboot with the vga attached to the nvidia port...

now...u r saying that u dont get a display from onboard when u have the nvidia attached...
in that case u need to test the nvidia in another pc...
if it works then it cud be a psu problem or ur pcie slot problem...
