shows the error with your video card... try updating drivers. its opengl error not sure if this will help though. if it doesn't work try removing minecraft and starting fresh

I just got my new computer, and it has all new drivers. So I'm not really sure, but thanks though!

Update your graphic cards, I was checking on the forums if someone else was having the same problems as you and here what I found out:
http://www.minecraftforum.net/topic/1028-orglwjgllwjglexception-pixel-format-not-accelerated/

People were recommending to update the video cards in order to keep up with OpenGL.

All of the information used there is out of date to my windows 8. That only helps if I had windows 7. I'm using the Microsoft basic display adapter. It works for everything except minecraft. And it says that it is up to date. This is so confusing

OpenGL: ~~ERROR~~ RuntimeException: No OpenGL context found in the current thread. What does this mean? I know that all of my drivers are up to date and I'm running the Basic Microsoft Display Adapter on my new ASUS Gaming Laptop. I don't understand why it won't work

Here is the latest crash update given to me :/ Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

Im getting almost the exact same crash report. My game only started crashing a few days ago.

Update your graphics drivers

My Minecraft keeps crashing i try Tekkit Classic and it just crashes here if this will help.
