Hello there everyone i have played minecraft for 4 years and have never experinced this. I installed shaders and action this day so idk if its going to be apart of why it doesnt work. Also when i was installing shaders i was having problems it didnt work.

The problem:
So when i open forge it gets to 2/7 and doesnt open then i try normal 1.8 it opens. I then try to join a server some times it will stay at a screen where it is just the grass block background or ill get into a server and just be frozen.

If you need more information then say in the comments thanks.
