FT8 issue after MSI mama board Bios & MSI driver update

[dave30019]

have a Flex 8400 SSDR 4.2.20, AetherSDR 26.6.5 and tried 26.5.4. The BIOS update went well, tested FT8 with WSJT-X v3.1, no issue. After I updated the MSI chipset, HD audio, Bluetooth, lan drivers, etc I had a FT8 issue.
Now I get 5 to 15watt spikes on transmit, on SSDR and Aether. I use TCI and on SSDR DAX/CAT.
I opened the Network tab and monitored the different graphs and saw NO issue while transmitting. I disabled the HDAudio driver in BIOS, same issue. I no longer see the RealTek HD audio driver in Device Manager since I disabled it. Same issue when using FT8.
I also added a bunch of ferrite cores since I looked almost like RFI. No change. I disconnected various pieces of hardware, cabling and broke things down to the simplest cabling, same issue.
Any help would be appreciated.
