BSOD (Blue Screen Of Death)

I have experienced few BSOD last week, after updating some of my device drivers on my workstation Windows 7 SP1 (x86). Since I was updating from Microsoft update, i was not suspecting that there might be problems with updated drivers. So, I have scheduled checkdisk of my HDD for surface scan, suspecting for bad sectors. Fortunately, my HDD was free of bad sectors, so I decided to examine the crash dump file using windbg. For more info how to obtain windbg, how to read small memory dump and how to setup symbols please check Microsoft articles : http://support.microsoft.com/kb/311503 and http://support.microsoft.com/kb/315263 .

Here is the output from my minidump :

---------

From the output I have noticed that BSOD was caused by the Nvidia video card and graphic driver nvlddmkm.sys. So, after updating the graphic driver with latest drivers from Nvidia site, case was successfully closed.
