GPU won't display on main PC

[VeteranX]

I am running into an issue here with my display. When I try booting my pc my computer posts but monitor does not detect display from the GPU. I tried using my main GPU on a different system and the display works fine. I tried putting a different GPU in my main system and the display works fine there too. I’ve tried using a different display cable too, but my main Computer just wouldn’t pick up the display when I have the main GPU in the system. They’re both low profile cards and don’t require external power. Please try suggesting me any possible fix to this problem.

You have post on a forum asking for tech help but have provided zero information about the computer or its hardware, not sure how we are expected to help in all honesty.

If you have no display the computer has not passed the power on self test so has not POST.

I have a Dell vostro 460 with an i5-2320 with 8 gb ddr3 ram and a 350w psu. The graphics card I am using is a low profile gtx 750.

I have tried changing which port the cabel is connected to after booting the PC and the PC seems to be running using the integrated Intel hd graphics.
