Clean install sounds like the next step. If the clean install solves the random freezes, it's either a corrupt preference, or an extension conflict.
Don't add back everything at once, do it in batches of 5, and see when the problem recurs. Then it's narrowed down to the last 5.
Another thought...and one of the others here may correct me.....but are your "regular" mouse control panel and your Microsoft Optical Wheel mouse CP and the Kensington mouse CP enabled? I ask because on my 6400 and my Imac I had to disable the "regular" mouse CP due to random "weirdness".
