I had a couple posts back asked you to consider getting your post count up, because I would like to privately send me the mini dump file so I can look it over.  You need to be at a minimum of 25 posts for that to be able to happen.  I again suggest you get some more posts credited to you - review some songs in the songs forum - jump in on some threads in the Coffee House if there are any that interest you.
 
Additionally, I don't know a thing about these 'Scan it Fix it' kinds of programs that are out there - like the one or two that you seem to have run on your system.  I don't know if those are helpful or harmful to your system settings, nor do I know what sorts of things they have changed.  I am quite leery of them myself, and would never choose to run such a program on my computer.  I would instead research individual issues and get up to speed on any potential changes as a result of my research.
 
I DO believe a solution can be worked out - but you could end up with a whole bunch of NEW issues if you keep letting unknown applications apply a bunch of changes.
 
I will check back in a couple of hours to see how your post count is coming along at getting up to 25 posts.  Once you can send and receive private messages, I will give you an email address and instructions on sending me a dump file that I can look through, to see if I can figure anything out that will help you get these issues resolved.
 
OK?

Hi Bob, I shall work on getting that post count up.
 
I too will not usually run these so-called fix-its - I have never had one of these on my machine until now, and I must tell you it is purely from frustration that I gave in and downloaded this stuff!  I cannot claim to be a geek on matters computers very much, so I had to do something I thought would help! Online reviews of the iolo s/ware appeared to suggest it was the best out there (PCMag etc...), but I did do some small amount of research in to the efficacy of these programs.
 
Anyway - yes, the post count.  Thanks.

Ananth - Is the FireWire port you connect your M-Audio AI to provided by the MB, or are you using an add-on card for FireWire?  Either way, what drivers are being shown for this in Device Manager?
 
Have you tried completely uninstalling the M-Audio drivers and leaving it unplugged during reboot and SONAR startup?  Please do.

I understand about prior experience.  I'm asking you to try things that may lead to additional clues.  I'm especially interested in the firewire port details.
 
Also, I haven't seen this specifically mentioned, but when you attempted to go back to Professional, did you go back to the exact release/version that was working well for you, or had Professional also been updated to a newer release?
 
Another attempt at getting clues ... you could install Professional again and without running it, roll it back to where you were when life with Professional good.
 
Again, I'm not blaming anything at this point.  I'm trying to help develop additional clues about where the problem might be.
 
I know it's hard to hear, but there have been updates to software in the past where performance improvements in the software ended up exposing driver bugs that hadn't shown themselves previously.  I realize you have a bunch of other software that doesn't have problems, but none are going to be as demanding or as close to your audio hardware chain as a DAW.
 
We have to keep coming at it from different angles until we find a way to expose the source of the problem.
 

BobF, well I went back and reinstalled Professional thru CC.  Rolled back to the 2016.06 version, the earliest I could find one could roll back to.  I don't recall what version was running when this worked back before my upgrade to Platinum.
 
Error (BSOD) still persists - it is the ntoskrnl.exe driver.  This has been the culprit the last many times I have attempted to fire up SONAR.

BobF, thanks.  Wow - this is going to involve some major surgery!  I get your point - eliminate add ons and 'outside devices' step by step until we get SONAR running properly, then work back and see if we can find out the culprit!  I was really hoping it would not get to this point!
 
Wonder if anyone else has these issues?  Only few comments from other forum members - so I would think this is pretty unique!
 
BobF, I will likely get down to complete what you are suggesting - but not immediately!  Thanks for the help.

I haven't seen many folks that have problems this deep and difficult to isolate.  Of the few, I think some of them have been Win7 upgrades to Win10 that would never behave properly on Win10 no matter what was done.
 
The above sounds pretty major, but it's easy stuff to do that's easily put back to the way it is now.
 
I sure hope you get it worked out soon.

In the meantime, I am also going to wait and see of Bob Bone has some other work arounds, he has been a great help this far as well.
 
Bob Bone?  Don't let me down!
 
Thanks all of you, really appreciate your assistance!

 
WOW - no pressure :)
 
I JUST got home from spending the past 8 hours helping to drive my roommate to the emergency room for a broken ankle - LONG day, so I will jump back into this first thing tomorrow morning.  
 
The landlord was working under the house in the crawl space, and the hatch to get down to it sits in the kitchen, DIRECTLY in front of the door leading to the laundry room.
 
My roommate did not know the guy was down in there, and walked through the door carrying bags of groceries, and stepped right into nothingness and fell straight down a good 4 or 5 FEET.  I had to help pull him out of the hole (with my multiple herniated discs in my back and neck), and then after bandaging up the bloody parts of his elbow that needed stitches, ran him over to the ER and all that. 
 
OK - so I DO promise I will try to further assist first thing tomorrow, as I am not likely to leave my chair or bed through the entire day, and happy to help :)

Was just thinking about these hardware conflicts.  Not meaning to sound totally negative, would the SONAR folks have not tested their s/ware for all these?  I mean, the Creative PCI card is a common one on a lot of machines, or so I think!  There is no mention anywhere, I believe, of possible issues like this when SONAR specifies system specifics for running the s/ware! I am now just at the rant stage - not having had any luck whatsoever - until, as I am being advised, I go in and perform major surgery on my system!  Woe is me!!  Thanks for everyone's comments and suggestions.

Thanks Bristol_Jonesey.  Hmmm, interesting!  By dedicated interface, would my MAudio Profire 610 classify as one?  This is firewire connected.

Forgive my ignorance!  How do I find out which chip set is present?  System devices?

The program IS still being maintained, and they give you a limited function version for free:

A couple of the fancier features are not available, like batch execution in DOS, and the ability to save reports in XML or as I think a text file, but you just want to see your chip set for the Fire Wire on your computer - so I think that would work fine for you.

did you try this ?

Hi - I saw you had posted earlier that you checked your device drivers for latest updates, BUT, in the video, they actually CHANGED the device drivers to use a different one.  
 
I did not see anywhere that you posted having actually followed the above video.  Please watch it and follow the instructions there to see if that helps resolve this.
