The A7V itself is a fine motherboard which hasn't given me any problems at all. I'm currently running two systems with that mobo, and both are incredibly stable (and not anywhere near burning up

).
It might be a problem with the combination of the A7V and your power supply, but I haven't heard of this happening from anyone else, so I'm not sure if this is correct or not. Still, the A7V is a great motherboard, and it's a shame that you've had such bad experiences with it. :frown:
Good luck in the future.
