|access violations are when a driver that has been loaded into memory decides to go rouge and step into other programs memory boundries.|
This can make for a OS that finds itself standing on a straw, on a tight wire over hanging a pool of hungry parana. To say the least there are a number of safeguards in place that prevent the total collapse.
If the newest driver doesn't work then the next trick is to try is go to an older version. I have had great fortune going to an older more stable driver.
This IS assuming with your new install you have done all of the updates and service packs. Otherwise the error is due to not having these installed.
