Minecraft Forums

I was trying to log on to Minecraft but it would crash seconds after it loads and I've tried to use a older driver,update my drivers, delete minecraft and java and redownloading them. I still don't know how to fix it and its been doing it out of no where.

Here is the crash report:

Open the options.txt file under the .minecraft folder and change "fullscreen" from true to false.

Alternatively, delete the options.txt file.

Thank you so much, it worked
