Kernel panics on a 2010 Macbook Pro

[irishgrizzly]

Yesterday when using my 15" Macbook Pro under a heavy load (watching a HD movie + several background tasks) the display froze on a still image, couldn't forse quit, so had to hold down power button to restart.

Now when I use it, it does the same a random intervals.

So far I've tried;

• Formatting the HD and reinstalling the OS.
• Booting from the CD and doing a HD repair/check. It comes up OK.
• I've tried to do a hardware test (holding "D" on the install disk), but it always freezes before it can fully boot.
• Booted with just the 2GB stick of RAM installed, then wit just the 4GB stick to see if I had bad RAM.

I'm thinking that it's either a problem with the logic board or the RAM. Thinking it's not the RAM or I wouldn't be able to run it for any time.

Any ideas what I should do next? I'm tempted to try another HD in it just so I can rule it out.

Here's the start of the crash report. I'm thinking it's the graphics card or the logic board...

I had thought it may be this;

MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

Symptoms
Apple has determined that a small number of MacBook Pro (15-inch, Mid 2010) computers may intermittently freeze or stop displaying video on the built-in display or on an external display connected to the MacBook Pro. In this situation, you may also see a restart warning message before the video is lost or the display turns black or gray. Affected computers were manufactured between April 2010 and February 2011.

So I called Apple and they advised me to bring it into the nearest authorised repair center. After leaving it with them I got a call from them saying that it passed all their hardware tests and that they couldn't replicate the fault, even after putting it under heavy tasks and leaving it on overnight. Said they applied all the updates and that that may have done it (I was running a full updated Lion before installing SL from the discs).

I'm not sure this will be the end of it
