I was having the same issue. A week or so after continuously having the problem, I noticed a graphics patch in Windows Update. However, I do keep my drivers up to date from Geforce.com but this patch I guess brought it up to speed even more? I used to be at a January 2011 update and it took me to February. Keeping in mind that the latest patch I had installed was from March 2011 from Geforce. After that, so far, no more ACCESS_VIOLATIONs. Also, new patch came out this week from geforce for Nvidia Updates, which may help as well! I didn't bother checking to see if RAM was in issue but if I come across the error again, I'll look into it!
