When did this start happening?
Has there been any changes at all - software &/or hardware-related - since this problem began?
What's the exact model of this PBI PC? I'm interested in the the long code beginning with PT.
I once had similar driver conflicts between Creative soundcard drivers & ATI GPU drivers. One or the other would work normally, but not both at the same time. I think I eventually resolved it by changing the sound/GPU drivers - used older driver versions that didn't clash. G
