Random bluescreens W7 64bit

First time I built a computer and wasn't expecting things to go without a hitch (was hoping though  

Anyhow, I have been getting random BSODs for a couple of weeks now. At first I found an issue with Avast! and replaced it with AVG but still receive random blue screens. I have run Memtest86+ multiple times on the RAM but receive inconsistent results. Running against each stick of RAM I receive no errors and other times I receive some errors (same with all 3 sticks in). I removed the motherboard and carefully inspected for bent pins but did not see any. I have tried booting with 1 stick in each slot for each stick of RAM and all boot without issue. All drivers are up to date. Also, I have also run every form of chkdsk on both HDs. Below are my computer specs, the BSODs, and information included in BlueScreenView.

I am new to the forums so please let me know the proper protocol for linking to uploaded RAR file with minidumps if those are needed to help further diagnose the issue.

Any help is appreciated. Thanks!
