To put this in chronological order, I opened up the GTX 1050 TI and set it on my desk, (this next part was probably my mistake). I went to Device Manager and deleted my old driver (this driver was for the gpu that came with my computer and was built in, you couldn't remove it), the screen went black and I decided to turn my computer off and insert my new graphics card. After a lot of trial and error I finally managed to insert my graphics card into the PCIE slot. I plugged everything back in and then when it booted up it only showed this message, "PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE(S) FOR ALL GRAPHICS CARDS" and this is what I think. Since I deleted the old gpu driver. It no longer sees that as a gpu, it doesn't see my gtx 1050 ti because the drivers and installed for it, not because the power chord isn't plugged in. I think what I would try is get the gpu out and then see what happens. In conclusion, I could remove it and see what happens or do something else. What do you think I should do?
UPDATE: The PC no longer shows any display but the gpu fans are moving
