Sir Les, take a break!
I did try to start it in "Safe" for Sonar mode by holding Shift key (not Windows Safe mode). It gives me one extra window- when it opened first time, it usually says, "Sonar will personalize your settings now"- well- it says this, I say, "Ok", then the error message of "SONARPLT.exe stopped working" appears. It is pretty bad.
And yes, all the drivers from Asus motherboard web site were installed, including Chipset, audio and video.
This is the drivers page (Windows 10 64bit).
https://www.asus.com/us/Motherboards/RO ... _Download/Now there is some weird audio monitoring software that got installed- I am not near that computer now to name it.
I installed
Realtek High Definition Audio (WHQL)
(Adds Advanced mode in Sonic Studio for Audio Routing Function.) ???
Realtek Audio Driver V6.0.1.7960 for Windows 7 32-bit & 64-bit, Windows 8.1 64-bit, Windows 10 64-bit.
Looks like they released new version of Chipset on 2/8/17, which is a hope- might of been something wrong with original- I will install it tonight when I get back home from work.
What else am I missing? Thank you.
