Casimir Engine

Hi. I've scoured the discussions to try and find a similar issue to the one I have but so far no joy. I broadcast from a laptop running Windows 7 and have found over recent months that i get skipping during a broadcast, as though a record is scratched and it jumps? I've dropped the bit rate, removed any external hard drives etc that might cause glitches, but it's still happening. I've used the system for over ten years without problems. I'm hard wired for wifi and get drop outs every now and again...
