I don't know much about PC's so I am sorry if this makes no sense, I was trying to take out my gpu and I removed the back screws on the IO sheild and because of the angle I pulled it out a part of it is trapped, also the gpu slot and it is stuck down, I tried putting it back in and pulling it out on both sides but it is really stuck, the GPU is a gtx 1080 jetstream.
