When I got home last night, I had a chance to look into this more thoroughly. It turns out that it was a memory related issue. When I ran memtest I was presented with a whole host of errors. This was a bit strange since this motherboard has been rock solid for over a year. That's when I noticed that the motherboard was detecting the CPU incorrectly and consequently setting the memory timing incorrectly. It doesn't make sense to me that this just started to happen out of the blue, but it did. It's an Asus A7V880. Anyone else every see anything like this? -- Brian
