Oh well, on the bright side, I never had the problem described with either of my laptops and my D100 before it died...
>is that the self-powered USB port lessens the work-load of the CPU which has to power the USB port on the PC itself
nooo, just no.
>I could always add more RAM to my PC too..
also very doubtful if you have anything over 2gb, and not too many apps running.
For any pc, get the latest drivers for everything (stable ones, provided no evidence on forums of stable ones being defective with regards to DPC latency, and beta ones fixing it) and the latest bios update. For crackling - If you have a laptop - disable all the power saving features (for pc/windows - in power settings set to high performance mode, in the bios - set the cpu to disable speed stepping), search for the laptop model and DPC spike issues and follow the instructions in the thread (generally involves disabling devices potentially causing it. E.g. on my old laptop crackling went away after disabling acpi devices - battery and adapter (probably just coincided with that disabling all the power saving fluff the easy/sure way))
