My father has a computer he uses for digital music recording. Recently it's started to instantly reboot whenever he tries to open one of his music files. He clicks File -> Open, picks a file, clicks the "OK" button, and BAM! it reboots. I don't know yet if other programs can open files without problems. Shortly before the problem started occurring, I updated the Norton SystemWorks from 2002 to 2003, and he installed SP2. Any ideas for problem or solution? Quickly, before he does something stupid out of frustration.
