Video card resets during gameplay

[TotalLamer]

First off, relevant specs...

Core i7 920 overclocked to 4GHz
MSI Eclipse Plus
Radeon 6970 2GB
Windows 7 64-Bit
Catalyst 11.6b

So I can do anything I so choose on the desktop without issue... but within the past few weeks, sometimes during gameplay the graphics card will randomly reset and when the screens come back up, the game I was running at 2560x1600 will be occupying one of my wing monitors (2007FPs in portrait mode) which obviously doesn't work. I thought at first it was a heat issue but even setting the fan to an obscene level and seeing temps in the 60s, it still happened. I left the PC off overnight and this morning, I can't even load into WoW without the card resetting. I tried getting a screenshot of the result afterwards, but when I opened the Snipping Tool, the card started continuously resetting until I rebooted the PC...

...thoughts?

Some more observations...

I tried underclocking to 750MHz... still immediate reset upon loading a game.
Then tried 500MHz... game loaded with no reset.
Then tried 650MHz... immediate reset upon loading game again.

I have a tri-monitor configuration. 2007FP - 3007WFP - 2007FP

If I disable my wing monitors (2007FPs) then I can get a game to load even at stock speeds on the core (880MHz).

Blargh, what does it all mean?!

I would guess (and it is strictly a guess) that you card doesnt like the different size screen when gaming. Other guess is that the secondary video output for the 2007FPS screens is failing

But then why would it work fine at 500MHz?
