Interesting. I've got a 3 year on-site parts/labor warranty, so the cost is covered. I just want to have some thoughts in hand before I crawl into the Dell support tunnel.

I don't want to leap in to a new mobo if it can be helped. Could it be a network broadcast storm? I didn't check the network traffic (but I will if it happens again). It's got an Intel Pro/1000 MTW card connected to an unmanaged gigabit switch. We're at the back side of a relatively slow link (802.11g) from the rest of the network, so there's only so many possible candidates for fast junk data.

I'm just baffled.
