Hello,
hi guys i changed something on my graphics card and now it says input not support how do i reset the card
 
I assume it is the monitor that says input not supported. You likely changed your resolution or refresh rate to something your monitor cannot handle. What you can do is boot in safe mode and change it back. While your computer is starting up you can usually get the option of booting in safe mode by pressing the F8 key on your keyboard.
