So the first thing to do would be to verify that you indeed are experiencing the same issue (and not an unrelated DPMS problem) is to keep using your computer and wait for a freeze to occur during usage.

Interesting, because this RV350 machine is my everyday desktop PC. It gets a lot of regular usage, and also a lot of intense CPU activity. And the DPMS-related freezes are the only ones I have seen.
