Question Gpu no longer displays on monitor after disconnecting gpu while PC was on ?

[RATProdYT]

So today when I was using my PC I wanted to see if my backup gpu was better than my current gpu, so I disconnected my current gpu from my case while the PC was on, and the PC turned off. Then when I put my current gpu back in after testing my backup gpu my current gpu wouldn't display anything. I have tried resetting, I have tried cleaning ports and HDMI cables, I have tried different HDMI cables, I have also tried other cards and monitors and those worked but it seems that my current gpu won't display anything on my monitor but the fans spin, and I examined my card and I couldn't find any type of damage.

I'm starting to lose hope with this card, I'm using a gt 1030 , 16gb ram, 2tb hard drive, I don't know my psu.

If anyone could help me fix my card, I would be greatful, I'm just hoping I don't have to buy another gpu

why would you remove a gpu while the pc is on?

I don't know I assumed it wouldn't break anything but I'm guessing it did, it seems that there is no visual broken things on the card but it displays nothing

turn the pc off and test with the old gpu?
could be the motherboard that got fried.

I tried my other gpu and it worked with my riser, but it uses vga, so I don't know if my HDMI port on my gt 1030 is messed up or not
