Minecraft relies on OpenGL through Java. Outdated or corrupted GPU drivers crash the javaw.exe renderer process.

How much RAM should I allocate to stop javaw crashes?

Allocating between 2 GB and 4 GB of RAM prevents out-of-memory crashes for most Minecraft versions.

Can antivirus block javaw.exe?
