Unless you have added a mod or altered the code, you have some kind of critical problem, probably related to your OS or hardware, but eliminating the possibility of an openGL problem doesn't narrow the possibilities much. I don't even know your OS. Make sure your drivers are up to date as well, otherwise GPUs don't work as well as you may expect.
I recommend trying to screenshot(alt + PrtSc, on Windows will only screenshot the selected application) the terminal(smaller window) before it closes, then paste the picture in something like Windows Paint. Either save and post the image of the errors or use the image to type the errors here. That will provide us with better details to try to help.
