Does my video card have a problem?

[Jufghd]

Why when I install NVIDIA my monitor shut's down? I dont know if my Video Card has a problem. and everytime I turn on my cmputer some letters are color pink. but past few years my computer works properly without changing any parts of my computer.

Monitor shuts down for a second because of the update to graphics drivers. It says this in the installer.

I'm not sure why your letters are pink. Try uninstalling all drivers and try again? Could also be a faulty GPU, cable, monitor.
