DAC losing SPDIF signal when I spark my gas stove!!!! Please help

I just upgraded my DAC from a MSB link DAC to the Bryston BDA-1 based in part on the glowing review here. It sounds fabulous except...

 

When my gas furnace starts and when I spark my gas stove to light it (both on different circuits than my computer and my DAC) the DAC loses the signal for a half second. Very annoying since the furnace is going on and off frequently.

 

I'm running:

Win XP

Mediamonkey with Wav.out plugin

M-Audio Delta 1010LT sound card

SPDIF output

Bryston BDA-1 to my pre and amp etc.

 

I've tracked the problem down to the computer since I can swap the computer for a CD player and keep the lock on the signal no problem.

 

My old DAC didn't seem affected at all so maybe it had a higher tolerance for errors or noise in the bitstream.

 

I don't have a UPS or Line filter on either the computer or the DAC.

 

I'd appreciate any suggestion. I'd not sure if I need to change sound cards, drivers, power supplies, OS, ???

 

Thanks for reading,
