I thought a good place to start is with my last BSOD. These as well as just plain system freeze ups occur at random times and while doing random activities, however, they predominantly occur while I am playing World of Warcraft. Since I had the crash dumps for the last couple of BSOD's I have included them. The freeze ups are even more annoying in that as far as I can tell do not create any kind of crash dump data.
While playing WoW they are very random. They may not occur all day or they may occur 2-3 times within a span of 30 minutes. I have done system clean ups, I've done memory checks and I'm running out of things to try.
I sure hope that you will be able to help with this.
