i wanted to upgrade my dell insprion 570's video card from a geforce 8400 so i bought a geforce gtx 750 ti, come to find out i needed to upgrade my power supply before i could use it. i finally upgraded my power supply from a 300w to a 430w. i tried out my new power supply with my old video card and everything works just fine. i tried using the new video card and my screen remains blank after i turn on my computer, it doesnt even show the post, but everything else is working, the keyboard, mouse. i tried connecting my monitor to the onboard video card while the 750ti was in but i still get a blank screen. i take out my 750ti and everything works just fine. i tried unistalling my 8400 drivers, disabling the 8400 drivers, disabling my onboard video card drivers and even changing my resolution to the lowest and still nothing. i even tried doing all that and booting in safe mode using msconfig and setting it to automatically boot up into safe mode with the minimum requirements. can anyone please help me

the video card does not have a place to connect anything. from the looks of it, it just goes into the pci slot

Okay I see it does not require extra power.  Which connector are you using on the back of the card.  Did you try plugging it in to the other DVI connector?  Or are you using HDMI?

Yes but are you connecting it to the black or the white dvi connector.  Did you try them both?  Does the fan on the video card spin when you turn on the computer?

Do you have more than one PCI slot that it can fit into?  Maybe try the other slot? Also make sure that it is seated completely down and locked down with the clip.  Only other thing I can think of is maybe you got a bad card.  Unless someone else here has an idea.
