BCCode 124 in 2 games

While playing Minecraft or Hearts of Iron III, I sometimes get a bluescreen for no apparent reason. I've uploaded everything that can help you: Problem description: http://pastebin.com/XMWH5erd DMP file: https://docs.google.com/file/d/0Bxq... sysdata.xml: https://docs.google.com/file/d/0Bxq... My system is: CPU:AMD Phenom II X2 545 RAM: CORSAIR 2x2GB DDR3 MOBO:ASUS M4A785T-M GPU:AMD Radeon HD 5750 Vapor-X PSU: Seasonic 660W OS: Windows 7 x64 The problem ONLY happens in Minecraft and Hearts of Iron 3. I've played games that are quite a lot more graphics-intensive, but I've never had any problems.
