Macabre,
This is a BIOS setting you need to change. Hold down the [del] key (that\'s usually what key it is) while your PC is booting. When you get into the BIOS menus, there\'s some kind of setting that allows the PC to wake when it hears a ring on the modem line. Sorry, I don\'t know exactly what it\'s called, because I\'ve never used this capability. The feature is usually disabled by default, so I\'m surprised it\'s happening to you.
BTW, I\'m sorry I haven\'t replied to you regarding the mp3 file you sent me. I really liked it, and I thought your band sounded very professional. I\'m not in the record biz, so I can\'t help you out, but my brother-in-law (schwager?) is a professional musician. He was the bass player in the band Badlands back in the late 80s/early 90s. Maybe he would have some advice for you.
