I had a second p5q-e crap out on me last week, it was a RMA replacement "newer version" board, 88M0A something.

I was just watching highlights on nfl.com, computer instantly shut down, restarted, but would not post ever again, although it would power up. I tried replacing the mobo with a p5q deluxe and everything is working fine again. I have no idea what the heck happened to the board, it was just like instant death.
