Hi MistaRip,
I believe that the culprit is faulty ram. One minidump may be crashed by ZA and your timestamp of your version of ZA is 43798224. I search google and there has no hit relating to this version has known bug. Anyway you can un-install ZA and install sygate firewall for problem isolation.
