VDDC heat causing instability?

post #1 of 2
Thread Starter 
I've been playing Darksiders, and it will run like gold for a while, then freeze up, as if the video drivers are rebooting themselves. The game freezes, then a couple seconds later, the screen goes black, then everything returns to normal. It will do this once the VDDCs on my HD4870 reach about 80C - I need to get some better cooling anyway, but is it this that's causing mycard to be unstable?

Use a can of air and clean any dust on the mosfets, chokes, etc on your video card. Then clean the HS and fan.
