Unless it is one of the new V-series, your PSU is most likely not able to hold up its end of the log, so it wanders out of spec until your system crashes. A quality 550W PSU is enough for your system, but CM offers mostly mediocre to bad PSUs. Unfortunately there would be few ways to test this, unless you have a lower-powered graphics card to install. You might artificially lower the clocks of your card some.
Another possibility is that your VRMs are overheating, although I'd expect this to cause lags but not crashes. Your liquid cooler does little or nothing for motherboard components. Make sure you have good airflow through your case, and maybe add an Antec SpotCool to point at the VRMs.
