    I did a AHT today and received this error.

    4SNS/1/40000000: Th0T-73.375

    I can't seem to find anything related to this already on Google or on Apple's support. Does anyone know what this could be?

    This might not be related but I've been experiencing similar problems with those in the nVidia 8600 thread. I'm getting artifacts and messy/fuzzy scroll down menus, and system freezes that will not budge unless I force a restart.

    I am running a 2.4Ghz MBP with 2 GB of ram running Leopard. I also have nVidia 8600m graphics card with 256mb of ram.

    Search for this only 4SNS/1/40000000: and google returns a lot of results. Maybe you'll find something, however, I think you should call or visit Apple as the display artifacts are most likely indicative of a serious issue.
