BSOD caused by atikmdag.sys (AMD driver) ("MEMORY_MANAGEMENT")

I just got a BSOD (blue screen of death) this morning. First one I've had in a while. Looking at the crash dump in BlueScreenView, it was apparently caused by atikmdag.sys, which I believe is my AMD driver. Is this correct?

So my question is, what steps should I take to diagnose the problem, and make sure it never happens again? I was using Catalyst 13.3 Beta3 when it happened, and I've decided to roll back to 13.1 WHQL for now. I will be hard to conclusively determine the actual cause of the BSOD though because I get them so rarely.

From what I've read online, worst case scenario is that I actually have a bad card (which I hope isn't the case... my card seems to have been working fine for the most part, anyway). Best case scenario, on the other hand, is that it's simply a corrupt driver install and I need to re-install my drivers. I'm always extremely thorough and clean when installing new drivers though, so I'm not sure if that's the case either.

Also important to note: The BSOD happened when I was simply browsing the internet. I didn't have any games open. I would maybe blame it on my overclock (1100/1400), but the card wasn't even in 3D mode when it happened. I've stress-tested my OC for quite a bit and it seems stable. I don't think it's my overclock.

The bug code from the crash dump is actually labeled "MEMORY_MANAGEMENT" though. So... maybe bad RAM is another possibility? Admittedly I haven't tested my memory with MemTest86+ yet, but my computer's been running pretty much solid for the past few months I've had it, so I thought I was in the clear.

I have a 7870. Any advice would be appreciated. I'll update if I get another BSOD, but who knows, I might not get another one at all, and maybe this was just some sort of fluke.

I also get errors with atikmdag.sys whenever my A8-3510mx overclock is not stable( I know I am stupid for overclocking a hp notebook). So, I raised the voltage and haven't had any errors since. It is highly possible your overclock is not stable, even if there is barely any load on your gfx card.
