Hi, i have recently upgraded my processor to a core 2 duo E6700. I previously had a Celeron D 356. After the upgrade, all my games are now crashing and freezing. For example, Minecraft runs at almost 200 fps on max settings, but after about 5 min, i get this wierd colorful render distance. Or sometimes, my screen will just fill up with colorful pixels. I know none of my components are overheating via hwmonitor. Also, i sometimes get this: http://nvidia.custhelp.com/app/answers/detail/a_id/3007/~/opengl-message-%E2%80%9Clost-connection%E2%80%9D So what could be the problem here?
