I installed a GPU and no boot chime or video

I installed a Nvidia k4100m on my iMac and now I I’m not getting video or an even a boot chime. Is this fixable?

The 2011 doesn’t support NVIDIA GPU’s, you need an AMD GPU natively.

While one can install the Nvidia K4100m MXM boards, there is quite a lot of steps to make it work, it’s not something I recommend any more as there are quite a lot of used systems with better graphics today with better CPUs as well.

But if you’re hell bent give this a YouTube a view k4100m vbios available for 2011 iMac GPU upgrade!
