    Unknown error on L1 -> L0 (Win XP SP2)

    I've been getting many of these errors over the last month or so. Using the argument "Unknown error on L1 -> L0 ", I get only 1 hit on Google (and which appears to be in Dutch) and no hits in the MS KB.

    Does anyone have any clues about this message?

    The Dutch thread that you found (Verschillende problemen) doesn't come up with a solution. The person who started the thread has a whole series of problems with his PC. The general feeling is that the power supply is too small to handle all the hardware in the PC.

    Are there any other log entries at the same time that may give you a hint?

    Most likely you have a problem with your nVidia video adapter (nv refers to nVidia).

    In that case, the error means that your video adapter must change mode from L1 (3D low power) to L0 (2D) to keep the same clock frequency.

    Try to download and install the latest driver from nVidia Driver Downloads
