Question Green vertical lines/disabled display adapter

[Ryhinehart88]

To start with, I am not very tech savy and my computer is about 10 years old. A few nights ago I was enjoying myself with a few drinks and the night became a blur. I awoke to find I had dismantled my computer for some reason. I put it back together but suddenly there were these green vertical lines on any monitor I used and the display adapter was disabled (NVIDIA GeForce GTX 950). Any attempts to enable it causes the computer to not even startup; instead I get a black screen with a blinking underscore. Disabling it is the only way I can login to it now. I can't play any of my games now, nor can I even open ASUS GPU program. I wish I knew what I did. Can anyone help???
