Hi, I've been trying out different "security" programs for a while now, and the only thing that is consistent are BSoD-s. I tried, Kaspersky Internet Security 2010, I tried Norton Internet Security 2010, and now I'm trying Eset System Security 4. BSoD is always caused by the same thing. 'ntoskrnl.exe' and the problem is (page fault in non paged area). It is 100% always that. They happen on a random basis, two times per day or even once every ten days. And never, never when I play games. Thing is, when i uninstall "security" program and put a regular anti virus (Kaspersky, Norton or Eset), and use a win firewall, everything goes back to normal and computer works perfectly. I also tested hard-drives, tested memory (thoroughly, for a 12 hours at the time, and a couple of times). I just don't know what to do anymore. Please help. I use Win 7 Ultimate x64 with regular updates. Please tell if you need more info.
