Why does Minecraft keep crashing when I join a server? [duplicate]

While I don't have all the information as to the cause of the problem, the one thing that shows up here to investigate is the following:

# JRE version: Java(TM) SE Runtime Environment (8.0_25-b18) (build 1.8.0_25-b18)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.25-b02 mixed mode windows-amd64 compressed oops)
# Problematic frame:
# C  [ig7icd64.dll+0x6c933]

I found a bug report about this issue on the tracker. It's not a direct issue with Minecraft but a possible issue with the Java install or with the video drivers. In this case, this problem is more likely a video driver issue.

You'll need to update the drivers, but I do not know what you are running directly, but it seems to be an Intel driver. Using the following link, you can visit their website to download a update utility that should find and fix this issue. http://www.intel.com/content/www/us/en/support/detect.html
