Possibly faulty 6950?

The problem is I get this really weird system hang only when I do a certain set of actions. While I play Bad Company 2 everyone once in a while I have to alt+tab or alt+enter to do something in the background and to get out of full screen mode to do something on Command Center, Teamspeak or lookin something up real quick.

Here's what will happen: The screen will go black, ambient noises from the game will still play in the background, sometimes the noises will do the stutter effect as well. Then the noises will stop, screen will stay black for 1-2 minutes. Finally something will start to appear either a white screen first or white back ground with game in windowed mode.. Then slowly my system will come back to life and be fine... Time elapsed would be around 3-4 minutes.

Just 15 min ago, this happened again (the whole system hang process) but this time the screen smeared in colors and then blue screen with the physical memory dump thing.


Now a couple of things you need to know:

-This would usually happen after I played more than 3 rounds. The first 2 rounds or so I wouldn't have this problem.
- This also happens when I exit the game (exit game through main page) but only after gaming for extended periods of times (8+ rounds)
-Right before the white screens I will hear two window sound notifications that tell me a device has been unplugged (you know like if you had a usb stick in and you took it out, windows plays a default sound right? That one.)
-Teamspeak will disconnect (or timeout) then reconnect as my system gets itself together.
-I'm usually disconnected from the server that I was on in-game(BC2).
-I have Installed various versions of the drivers (10.10, 11.1, and 11.1a) resulting in no difference.
-Yes I did you driver Sweeper in Safe Mode.
-I keep my fan speed on Manual 50%.
-I never had this problem with my XFX 5830, alt+tabbing and alt+entering were instant.
-I haven't reformatted yet.. but will probably install a separate OS on a a separate drive to see if the problem persists on that setup if you guys think I should.

Sounds like the gfx card is crashing due to overheating..

Put the fan @ 100% and watch the temps while it happens.. also setup a log so you know the temps when it crashes.
 
At 50% fan, heat is not the first thing I would suspect with stock clocks. Just download gpu-z and use its logging feature while you game. That will give you alot more info to go on.
 
Sounds like it could be a hardware issue. Another thing you can try is if you have other power supply that is powerful enough lying around - throw it on and check for the same symptoms. Do this just to isolate any power issues and rule it down to the card. But yeah also check your load temps. Even 50% fan speed won't do much in a poorly ventilated case.
 
Does it happen when you play the game in window mode? So... does it only happen in that game... I usually test out a few games to rule out if it's software or hardware related. If say it's only happening in one or two games and everything else plays fine, then likely this is software related. I'm also guessing that problem you are having might be related to AMD's Powerplay feature that sets a different clock speed for desktop 2d vs 3D. So when you alt+tab it down clocks the speed to 2D and when you go back to 3D it keeps the 2D clock speeds. It's a long standing problem AMD has had and even Nvidia as to save power.

Yeah forgot to mention that this error occured with two different PSUs. First I had a Rosewill Xtreme 850 watt then installed the Thermaltake TPG-750 in yesterday and was still getting the same problem.

Never reallly tried it in windowed mode.. Because when in wondowed mode my fps would literally be cut in half... I use vsync and would get a constant 60 framerate.. but in windowed mode it hovers around 30.
