OK new update added. After I recorded the three sessions crash free, the very next day Sonar Froze again and then several more times after that. At that point I go so frustrated and I said Forget Sonar and shut down the DAW to look for a new program to buy. I was going to either purchase Pro Tools for Windows or Studio One 3.2. Over the past few days, I hadn't touched Sonar or my DAW, but instead was viewing YouTube and looking at what both Pro Tools and Studio One 3.2 could both do for me. Both were nice and each had it's advantages over the other in different ways. I downloaded a test product of each and ran them on my old DAW used for testing, this DAW has windows 10 and only 8GB installed. Both seemed to work well and no freezing (my major concern), but because they were trials, I couldn't use a log of plug-ins and there wasn't a lot of instruments to use. However, what I could see in Studio One 3.2 I liked, so that was the route I was headed to. I had scheduled this week to perform the uninstall of Sonar Platinum thinking I would never use it again, but wait a minute..., I saw a conversation on the Cakewalk forum site discussing the Early Access Program for the release of SONAR 2016.05. I never took advantage of this download. I saw a version of Sonar with the Tungsten theme and it blew my mind. I was still on 2016.04 so I asked about how to obtain the version of Sonar with the Tungsten theme from the Sonar community and I was directed to CC to obtain it.
After Sonar updated with 2016.05, I tested it out and the GUI looked great and I have not had a freeze during the entire weekend. I added my Audio Card back to Sonar Platinum and I still didn't have a problem. I kept stating and stopping the play and pause button on my MCU quickly, where I would get most of my freezing and nothing happened.
All weekend long, there has been no freezing. Sunday I ran Sonar Platinum basically all day long stopping, starting. pressing pause, adding loops, recording Bass Guitar, editing midi, using soft synths, comping, running mass plugins and not once has it froze.
As I said originally, it wasn't the computer, it was Sonar Platinum as I thought. After the update to 2016.05, Sonar looks good and is working well again. We will see what the future holds, but for now Sonar Platinum is welcomed back in the studio where it belongs. We've had some history from Sonar 2.2 XL to Present Times. I love Sonar, but it better not act up again or else.... 
that post was like a good book. good read man.
im glad its all good now. I cant say I agree that's its sonar, but good people find respectful ways to disagree and you are a good guy man.
I cant honestly say what I think your issue is because I don't know. I truly don't.
but in your case, im guessing a new update fixed some problem you were having. so in a sense, yes it was sonar...BUT.. because every set up is different, not all have those issues, like myself. I if ever rarely encounter any issues. I do however try not to do anything that will jeopardize my projects (save while playback is running, delete plug ins while the transport is running, exc) these are little things ive had problems with over time. however not the same in your set up though. pressing the button shouldn't give you a freeze :-)
so in essence, I don't think it IS sonar, but in your case it WAS sonar. does that make any sense ?
I know one thing, I got my MCU about 3 months ago, and I am so in to that thing its not even funny. I love how handy and easy it makes life.
John got me in to MCU many years ago when he recommended it. I just couldn't swing the cash for a new one, so I waited, saw one on Craigslist for 200. sent the link to John and he gave me a thumbs up (told me it was a good deal) so I bought it and I have been happier then ever, Shout out to John, ;-) thanks man.
any way Jesse, glad your still here man. most of all glad sonar is agreeing with you and your back to making music vs worrying about a crash, one cant make good music like that, very happy for you.
