BSOD's happening randomly without me seeing after leaving Desktop idle

[DeliciousSalad]

For about a month now my computer has been shutting down on its own.

It hasn't seemed to be hindering anything but it's strange that this is happening.

It seems it's the same issue causing it over and over since windows always talks about how it recovered from an unexpected shutdown whenever I turn my desktop back on.

Attached is the recent dump file, any help is greatly appreciated!

Update the network driver form Realtek .... get the 4th item of the list (that is the "Win7 and Server 2008 R2 Auto Installation Program" one) and install it.

For any further BSOD, post the complete set of the required data following the Blue Screen of Death (BSOD) Posting Instructions .
