[Support request] Black screen/freezing after about 2 minutes of play

I installed all the recommended mods and IC2 on a fresh MC today, but it keeps freezing and then going to a black screen.

I used MinecraftError, but it didn't give me an answer to what the problem could be.

http://pastebin.com/Sa3gMGb6 here's the error report from MinecraftError.
Please help

Thank you very much, I've been reinstalling MC and IC2 ALL DAY, literally. Good to know I'm not doing anything wrong and it's just Mojang being derps :p
