Please follow this post again and install a few different drivers, if there is no stability improvement we'll be looking for memory hardware problems.
As I explained in this post many memory hardware variants show signs which I have not seen back in the dumps except for the display drivers, this may mean that the RAM is causing the crashes even though MemTest86+ did not find errors (tests are not 100% as @Arc mentioned in this post). However that the RAM may cause the crashes is not being said with 100% certainty, it needs to be tested by replacement.
