I bought this used Gpu gtx 950 installed it updated the drivers everything but there were green line on the screen both before and after installing the drivers. At one point I shut down the pc and restarted and it worked for a moment no green lines while watching a video on YouTube the pc restarted an the green lines were back I noticed that nidiva panel won't appear or open. So I tried shutting down again it worked and the panel appeared and was opening but the pc shut down again and the green lines back at it but they never lift since then also no nvidia panel. Tried reinstall the driver everything nothing nothing works.
