PCIe x16 error

I'm sorry if I am not doing this right. I'll do my best, I promise!

 

• Describe the problem you are having in detail but without rambling. If your post is as long as this one, it's too long.
  
  -My computer beeped at me and then failed to start. I reinstalled Windows 10, managed to launch in safe mode. Fixed that. Installed every driver but the Nvidia driver which crashed.
  It would not boot except in safe mode and then only if I deleted the Nvidia Drivers with DDU.
  I decided 'heck it' and plugged it into the second slot ( Which after googling for an hour I learned is a PCIE slot! ) and it works.
  
  I have no idea what's happening or how to fix this? Did the first slot die? Is that a thing that happens?

Hey, I don't know if this helps but my psu cable is a bit wiggly where it plugs into the pc in the back. Also, I plugged the graphics card into the top slot and it worked all the way into windows and then it black screened and restarted. I probably need a new power supply huh?
