Intermittent BSODs Win7 fresh install


I just did a fresh reformat and install of win7 on my desktop. I made sure to get all the updated drivers for all of my hardware, but I keep getting a BSOD randomly every few hours. I cannot successfully reproduce it by doing anything in particular, it seems to be entirely random.

I have attached two minidumps that I had to zip because they are both around 280 KB unzipped. I would really appreciate any help in narrowing down what might be causing this so that I can hopefully have a stable system.
