Steam: Lockup, forced to restart computer

[Hypatian]

Aha!

I remembered last night just before I was going to bed that I had a similar lockup problem to this when I attempted to run World of Warcraft under Steam to get the Steam in-game overlay.

Today I'm playing with defaults settings, but the Steam overlay disabled in Steam config. It seems to be working so far with no mishaps. I will report back later this evening and let you know if it's still working.
