and "928: SecondLife.exe - Application Error" both say "The memory could not be read".

I believe my new vid card is about to blow up. I had this problem a few months ago and was unable to find a cure, outside of replacing my vid card. From what I hear, SL just loves to eat video cards!
Anyhoo, this is my last hope to see if someone knows what on earth is going on here. Is this a video card going bye bye? Is this related to the memory leak issue?
What I have:
Second Life 1.20.15 (92456) Jul 18 2008 10:58:42 (Second Life Release)

LLMozLib Version: [LLMediaImplLLMozLib] - 2.01.17175 (Mozilla GRE version 1.8.1.13_0000000000)
What I have done:
* Updated vid drivers to 6.14.11.7779
* Defrag
* Uninstalled SL, deleted everything, reinstall etc...
* ScanDisk
* Virus checks (just incase)

* Anisotropic filter is off
* Tinkered with VBO (on/off)
* Texture memory at 256

Any help would be appreciated!
