The problem started while I was in the midst of a LotRO game and things went from "slow" to "dead slow" to "completely nonresponsive." Several hard power-downs and reboots later, the thing is now so much dead weight on my desk. I'm going to keep messing with it for a bit longer, but I'm more than a little afraid that I have a $900 brick on my desk.
Y'know, at one point this time last month, we were talking about getting laurie_robey a new computer. Maybe we can get a good deal on a 2-for-1 special. -.-
More bulletins as events warrant.
