Changed the memory settings last night as directed by eVGA and Warcraft functioned as it should while I was online. However, it has functioned properly in the past for hours before crashing. So it will take more time to see if my problems are fixed. I'm skeptical, but who knows?

Just haven't had the time of late to play for hours :)

Well, I rebuilt the whole computer this morning. Took it completely apart and then put it together again. Switched from the P182 to the Coolermaster Stacker case for more air flow. I now have 5 120mm fans installed in addition to the motherboard, CPU and videocard fans. So I don't think cooling is the problem. I read on a forum that disabling NCQ could fix it, but it didn't. I'm not sure what to do now. Hopefully the eVGA forums will help.
