SmartSDR, MiniPC, WSJT-X.....RFI problem

I have a new MiniPC that I am using to run Flex. I have an issue with RFI getting into the PC and messing up WSJT-X. It didn't happen with the Mac. During transmission I hit "halt TX" but nothing happens. It apparently locks up things when transmitting. Any ideas? Perhaps some suggestions on chokes and placement? I am running Bose Companion speakers now and I get a hum while transmitting also. This is all new. It wasn't doing any of this with the Mac. By the way the speakers are not connected to the PC. Thanks for any help!

    Read this first http://audiosystemsgroup.com/RFI-Ham.pdf and then build your own chokes by following this http://audiosystemsgroup.com/2018Cook...

    Don’t ignore any wire going into and out of the PC when applying chokes. You MAY reduce kbd and mouse RFI by using wireless, but you need to try it to be sure the brand used does not suffer from interference from your transmitter at the frequencies you use. I have good luck with them, but then I run barefoot, and usually Less than 50W. Until I choked off my monitor video feed, the monitor would simply quit on 15m - PC worked fine, but I couldn’t see anything :-) Fortunately, pretty well any decent quality video cable has one or more chokes in-line - mine was cheap :-(

    Chokes only cure the symptoms, not the root cause. First step should always be fixing your antenna, by properly matching and feeding it.
