Random Blue Screens of Death?

I didn't know where to put this so I just put it here.

Hello I have a problem, whenever I leave my computer on for around 40 minutes or more idle, I get a blue screen of death. Here are my specs http://pcpartpicker.com/user/ThePCNoob2/saved/2Vpa can anyone find the cause and a fix?

need more information. Overclocks, what is happening when it crashes (I know you said idle, but are there background programs running?) and Temps. Can't really diagnose it if all we have is a list of parts.

There is not much running only Skype, Steam, and Utorrent. Also I am not overclocking

"40 minutes or more idle" maybe sleep issues scroll through this and see if it rings a bell
