Occasionally on boot up, just as the windows 98 screen appears, I get a blue screen and a fatal exception error message and instruction to press any button to continue. Most of the time this works and windows continues to load. Other times it will just lock up and I will have to shut down and restart. I am using an AMD K6-2 w/128meg RAM, 30gig hard drive. Window 98 second edition. After boot up all other programs seem to work fine. Any suggestions anyone?
