I've been using it for 6 years without any problems. A few days ago I wanted to play game. Suddenly the system crashed. Then I enabled the Use Nvidia high performance GPU option to get better performance. After doing this, I tried to enter the game but now I was getting GPU Shader 5.0 error. Gone. I tried many methods but it doesn't work anymore. A lot of things have been problematic lately, but this painful graphics card issue dealt the fatal blow.
