My recently upgraded to W. 98 system, (AMD K6-300, 64 Mb)
sometimes when shutdown, instead of the usual now you can turn off -- message, gives me a blue screen with the message that a Fatal Exception OD has occurred at
030F:00015AA, and on pressing then any key I get a black screen filled with a regular pattern of tiny dots, from which I can only reset. What is "OD" and can the cause be found and fixed ? Dan.
