Save As = Random Crash to Desktop

Hi there audiophiles. I have this on-going issue that occurs 'sometimes'. Today for example, I loaded a project and did some minor tweaking of an automation lane and before I went any further, I wanted to save a copy for my next edits. I selected 'save as' and Sonar just crashed to the desktop...no warnings or anything, just disappeared. 
 
I reloaded the project and selected 'save as' straight up' and it was all good. 
 
This issue seems to occur randomly and not always. Like yesterday, I had been editing a project and saving it to a day old version. I wanted to create a new file for the day's edits and did the 'save as' and CTD. Fortunately I've been getting into the habit of saving, saving before I practically do anything these days so no loss and restarting to save as worked okay. 
 
Anyone else have this happening? 
 
PS. This is like the 'opening a project' from the Screenset. On occasion, it will do the same thing. But after restarting, it's fine. 

Random crashes can sometimes be associated with a bad Hard drive/bad ram.
Have you done a check on them ?
 
Sometimes its a plug in but I find random crashes to be a product of the hardware or drivers.
Sometimes a poor/lost connection to a device and yes it could be Sonar not acting kindly with you wish I had more help to offer.

Well I spoke way too soon. Going back in time to an earlier version apparently didn't solve the problem, although it did however make the problem not as frequent I should say. So I have decided to go back to the latest Sonar Pro version. 
 
My Pc has more than enough power to handle processing what I record with it. I'm starting to wonder if when I record something if I am going to HAVE TO FREEZE THE TRACK in order to do anything else. The performance meter or whatever it is called in Sonar shows I am not even barely making it do much at all PC power wise. 
 
Something else I should mention, lately I have been using TH3 Overloud Full version and Mark Bass II from Overloud. I'm wondering if multiple instances of them when I record like say 2 rhythm guitars using it and add two lead guitars using TH3 overloud Full if there isn't an issue there? Should that be causing a conflict or crash? If so why? And if that is the case and you can only use something like that on one track what is the point of having or using it is what I am getting at, same with other VST's and VSTi's and such. 
 
Either way, it's just really irritating having Sonar Crash. I've stopped sending reports as of now, the reason why is I haven't heard NOTHING from Cakewalk at all, and apparently since buying Sonar Pro my 1 year of updates and tech support are up, and I find it rather strange that this issue began AFTER my 1yr was up. Either way. The way Sonar Pro is behaving I don't know if I can go on using it, too many crashes and I find it is causing me problems trying to concentrate simply to record anything because I'm wondering when or IF it's going to crash. 
 
I don't want to be forced to move to another daw, but at this point I have to consider it considering the situation and the lack of replies after sending about 20 or so reports, NO TICKET sent via email or nothing. AND I DO GET THE CAKEWALK EMAILS, NOTHING IS BLOCKED ON MY EMAIL that I use for cakewalk. 
 
Oh well, maybe somebody will find a solution to this problem. 
 

As usual, issues like these are hard to pin down. I run Defender as well and there may be a correlation. I've whitelisted Sonar but again difficult to know.
 
Yes the issue of ram/HDD. After a period of time when I get startup problems or net freezes, it's time for me to clean the contact points on both my video card and ram with Isocol. This fixes these kinds of issues for quite a while. I've also noticed that after deleting some messages in Outlook, when restarted later, those deleted files show up again. This doesn't happen all the time, so there could be some issues with memory/HDD. 
 
I guess the point for me in reaching out is to see whether other Sonar users have experienced this and whether it might point to something with Sonar. For me at this point, this issue occurs infrequently and apparently randomly and as long as I save my work before 'saving as' and restart, I can work with it, so it's not like it's every time but it also makes it difficult to reproduce. 

Just an update in my situation. I decided to start over and reinstalled Windows 10 "Latest public release whatever build it is" from scratch, I got it from the Windows SITE. This time I installed only Cakewalk software. So far it seems to be working great. 
Reason I'm replying here is because I wanted to mention that my previous installation did have "WAVES" and "ILOK" installed on it, I had like one plugin for WAVES which was "ONE KNOB LOUDER" and for ILOK I had "Eventide Ultra Channel" which didn't actually require the ILOK but it required the ILOK activation and the software. 
This time I did not install WAVES or ILOK. I have had problems in my case not just with SONAR but other software that I have noticed in the past after installing WAVES and ILOK software. This time I didn't install either and so far everything after a couple days is working perfect, no more crashes. So I am left thinking it may have something to so with those plugins, or perhaps the Waves or ILOK software or who knows. 
 
I backed this setup I have now to IMAGE backup after setting Sonar Pro up like I want it and the rest of my PC so if problems arise in the future it will be easy to get back to WORKING GREAT for now setup. 
 
One more change I did make, I disabled Windows Defender in the registry completely and now use Zemana Antimalware which so far seems to be working great for me. Much lighter than Defender IMO. 
 
So for whatever reason I was having multiple crashes those are some things I think that might have been causing them and so far so good. 
 
My PC was meant to be a Music Recording mostly PC anyway, although I do use it for a couple other things like checking the weather radar and a couple of sports sites, so I basically go to the same sites all the time and don't download anything new, just thought I would mention that for those of you who might be talking about security issues. I disabled the Windows Defender in case it might have been an issue to begin with and I also have the Zemana Alternative which I believe is light years ahead of WD in protection. Just my opinions either way. 
 
So, this worked for me. For now anyway. I can't tell you how aggravating it is to record a track and have to constantly be trying to save your work on every take in fear of losing it because of a crash. And yeah, you can turn on that auto SAVE feature but WHY SHOULD YOU HAVE TO? I know there could be power outages and stuff like that, but when your using it a lot it should at least work right most of the time ya know. 
 
I really like Sonar Pro, and I hope to upgrade to Sonar Platinum in the future, and the crashing issue was something really concerning me as I am sure it would others out there also. 
 
My entire point being, I can't say 100% for sure that THIS WAS A SONAR ISSUE and that's why I am mentioned my experience in the hopes it might be beneficial to someone else out there.
