My Minecraft keeps crashing on startup everytime I open it. I was trying to play optifine 1.8.9. I reinstalled optifine, didn't work. So I tried a different version. I hopped onto the latest version, it crashed again, but this time with a crash report. This is the report I got:
The game crashed whilst initializing game
The game crashed whilst initializing game
Error: org.lwjgl.LWJGLException: Pixel format not accelerated
Please help. Thanks.
