Yes for about 4 hours then started up again gradually becoming more pronounced with time. > To me it sounds like a physical phenomenon - not software.

The first time it happened I tried to reboot immediately but the boot wouldn't go past the SCSI bios part so I powered down and left the machine off for about 30 minutes and then restarted. After about 4 hours the sound problem restarted and when trying to reboot the machine it again wouldn't go past the SCSI bios part. I turned off again for about 5 minutes and restarted. That was about 24 hours ago with no recurrence of the problem yet!!! My suspects are in order of likelyhood: Mains electricity supply (although the computer is on an UPS). Faulty component somewhere. Software. I have never come across anything like this before but then I've not had a sound card before and with the speakers turned off there is no indication of any problem. I shall wait and see what happens over time. Barry Samuels
