I have looked at some of your dumps and it appears the Nvidia driver is involved in several of them. All of the ones I have seen seem to be related to memory, either addressing or corruption. Since you seem to have the same Nvidia driver I have, possibly something else is causing some bad data.
Could you tell us about your system, motherboard, type and amount of RAM, Video card,etc., so we can access your problem better? Are there any settings in the Bios for any video memory?
Does this happen in Safe Mode? Have you reverted to earlier drivers for the Video?
It seems from net postings, your type of situation has been around for a while. I have never seen it on any of my systems, so perhaps some comparisons might help.
Also, there is a sticky that enumerates the type of information which could be helpful for diagnosis. CPU-Z might indicate a problem with your setup as far as memory or processor.
