I've had this issue in the past but thought it had went away.  Seems like I have this happen every time
I get a project going and starting adding some loops from the media browser, then....Sonar crashes.
BSOD.
 
Typically, I've loaded 6-8 audio tracks and have dragged and moved around the loops as I'm
trying to get a loop based groove going.  I'm good for 20-30 min before Sonar crashes....every time.
I learned the hard way that I need to save my project every 5 min or so.....or else lose the work I've
done up to that point. Not running any VSTs, effects, or anything fancy.  My loops are all on an external drive
but I'd hope that doesn't matter.
 
My setup is Win7-64, 8 gig of Ram, AMD-6 core, Focusrite 2i4.  I have an Nvidia card with the latest drivers.
I have disabled by Norton Internet Security (even disconnected from the internet), no MS Office running, no
Carbonite running, no MS Firewall.
 
Any suggestions?  Thanks in advance.

typically when I hear "BSOD" I think bad hard drive.
it could be a number of things and it could be sonar as well, but with nothing really going on (no vst's, exc...exc..)
I would be looking at the HD and how old it is, its health. (both the OS and the external one)
you could try running in safe mode and see if it still happens, this would eliminate a VST issue if there is one.
but you said you didn't have any running so im not sure really. I suspect one of your drives.
 
 
try to keep a log of what happens right before the crash, this will prove critical in problem solving.

 
What version of Sonar are you running ?
 
I've never gotten a bsod running Sonar and can't recall anyone mentioning one here lately.  Might also be bad memory, bad motherboard.  Anything is possible.
 
Windows' system logs may show something amiss.
 
I have Sonar crash often enough, but that's the faded white screen of Sonar's death.  Also things stop working like the Now Time broken in two or missing parts, and Play that won't play, but closing and reopening Sonar always fixes those.

I agree with Paul 100%. I myself have had the white outs as well but never any BSOD's.
he brings up a good point too, besides the Hard drive issue that I recommended looking in to, it could be bad ram or a bad mobo,
*possibly even CPU overheating/not functioning to full potential.
 
 
software can cause BSOD's but more often then not, its system related to hardware, then to OS.

On the BSOD screen, there should be an error message. What is it?
 
For example, I was getting almost daily BSODs after upgrading to Win10. My error message was: KERNEL_SECURITY_CHECK_FAILURE. That is typically a driver failure. I was also getting the occasional notification from Win10 that the video driver had failed, and that Win10 had recovered.
 
I was going to wait on posting this as a new thread for a couple of days, to allow more testing time, but what I did was replace the original video card (an AMD Radeon HD7500) which came with my Dell XPS8500 in early 2012 with a Gigabyte GeForce GTX 750 Ti with 4 GB GDDR5 RAM. I had been updating the AMD driver with each new beta release, but my problems were never solved. So I replaced the card with a modern one.
 
So far, not one BSOD nor Win10 adapter failure notification in the two days I've had the new adapter installed.
 
Check your error message and Google it. That led me to the proper solution. Too bad it cost me money. 
 
Edit: For fun, here's something very close to what I took out and what I replaced it with. My, how things change.
