Right now I updated my graphics card with the nvida gforce experience and when it finished it put my monitor into an unsupported mode I can't get out of it. So what I want to do is just unplug the gpu from the psu and leave it in the computer. Will anything happen if I leave the gpu in and start the computer while it is still plugged into the mobo?
 

That wouldn't work so what I did was just unplugged the power to the gpu and then set a resolution with the moBo and then when back to the gpu and then changed it to a usable one from there
