I have spend hours trying to fix this and it's really starting to annoy me.
I did a quick search of the forums and couldn't see anything like this issue.

The game will randomly freeze while playing usually within 5 - 20 minutes, can't do anything but reboot.
CPU was running at ~80% on all 4 cores constantly. To compare, I ran Homefront at max setting and it was nowhere near this.
I then put Brink on the lowest possible resolution and graphics settings and CPU was still running that high.
Graphics card is 6950.
Other than the crashing the game runs perfectly.

Any idea?
I have never posted on a forum before either - that's how much I want to be able to play this right now.
