Hi, when i turn on shaders, they doesn't work. I mean when I click Shaders [ V ] in options , it doesn't work, like they're turned off, and when i go options again, they are turned off.

Shaders require hardware capable of them, if it turns off then it means your computer can't do them.

I on the shaders but whenever I do so my computer breaks down and makes fidgety images unto the monitor.What do I do to fix thee problem at hand?

Update your drivers.

yes but on older versions it worked
