Thanks! Will try it.
Had a friend telling me the D/A:s could be bad, but then the exact same thing wouldn't happen on both of them. I start up the comp first then both of them at the same time, maybe it's the startup routine as you said... Sounds much possible.
Didn't know they were sensitive like that.
One more thing. I have an accel card. Should I run the slave from the accel or both of them from the main PCI?
