I used to support Maya way back and when Maya crashes, the #1 tip is to solve the problem was to use Maya with default preferences. The location of the Maya preferences is noted in this article.
ENHANCED TIP: Please rename the preferences instead of deleting them!
"I would like to ask everyone to stop fully deleting preferences folders when trying to isolate an issue. If deleting preferences fixes the problem, we just lost the evidence of what caused the problem in the first place.
If there is no issue being investigated, feel free to delete them. But when investigating an issue, a better habit is to rename the preferences folder with a descriptive name. Maya will launch with default preferences after that. The renamed folder can be sent to QA/DEV by logging a case into Product Support. We can use preserved preference files many times to discover what was original software defect/problem." via Maya QA Ryan Harvey.
