Maya crash PLEASE HEL: Attempting to save in C:/Users/vladivpg/AppData ...

[vladivpg]

hope that someone has had a the same or a similar problem with Maya at rendering time:
Fatal Error. Attempting to save in C:/Users/vladivpg/AppData/Local/Temp/vladivpg.20120503.2242.ma
// Maya exited with status 1
I use to have it before with the previous versions of Maya all the way from 2010 to 2012 and I never managed to figure out what is the cause of it. Until now I have maybe more than 3000 crashes with this error message, it is about to ruin every single project that I have done with Maya. All the software that I use is legal. I tried to cleanup my scene: topology, UVs ... basically everything that is included with mesh cleanup tool and optimize scene size I got no warnings when I run render diagnostics. I turned off the triple buffering of my video card and I did tried to delete the windows prefs and maya.env ... folders in order to revert Maya to its defaults settings but there is no results. I am rendering with Mental Ray and I can upload my render settings and if someone can understand it I can also upload my last render log.txt file too.

I got a fresh installation of Windows 7 Professional 64 bit with Maya 2013 student license
my computer parametars are Dell Precision 7400
Intel Xeon 3.40 GHz
Nvidia Qadro FX 4600
8 GB ECC memory
