Hey everyone,
 
I am having some serious issues with using the Quad-Capture. I've tried what seems like everything. I run SONAR in as Administrator, I make sure Windows is not using the interface while running SONAR (that seemed to give it more stability). No matter what, the Quad-Capture seems to crash my PC, blue screen and all. Sometimes it will crash when I am just using the interface for iTunes or Youtube (but not running SONAR at the same time). I've tried both WDM and ASIO, WDM seems to be more stable but I still have crashes. Can someone please let me know what might be the problem?
 
I am thinking of purchasing a new interface in the hopes of cutting my losses. Can anyone suggest an interface they feel is rock solid while running SONAR? Something that's no more than $500, thanks in advance.

Have you updated to the latest drivers and system update?

What version of Sonar?

I have the latest drivers and system update. I've tried re-installing the drivers as well as SONAR, but the issue remains. I am using X3e. I have Platinum but haven't started using it yet since I have some projects that I want to finish in X3e.

Do you have problems if you stay off the internet and only run your computer as a DAW? 
Sometimes it's a bad idea to make a DAW multi task. 
Your asking for trouble when you use a pro audio system to play U tubes. 
Uncheck share drivers with other programs
And use your on board audio for that stuff. 
Or like me, I disable all other audio drivers and don't go on the net unless I'm updating DAW related apps. 

as far as answering your original post,
 
i would suggest these:

RME Hammerfall HDSP 9632

Focusrite OctoPre Mk II

Steinberg UR28M

MOTU 4pre

TASCAM UH-7000

Focusrite Scarlett 18i20
 
 

I am wondering if it is because you appear to have your audio interface shared between Windows and Sonar, that your troubles are occurring.
 
If you have not tried this - please try changing the Windows Default Audio Device to something other than your audio interface (I use my on-board sound).
 
Sometimes Sonar and Windows can fight over access to the drivers for the audio interface, if they are both set to point to them.  I can only recall this occurring for the ASIO driver mode, but others might know one way or the other if it could also occur for WDM.
 
All I know is that I always keep them separate, with Sonar and other music apps that would run only by themselves using the audio interface, and Windows using my on-board sound (or more likely pointing to the HDMI of either of my HDTV monitors).
 
So, please test out pointing Windows to use on-board sound or perhaps HDMI of a monitor, and have only Sonar pointing to the audio interface, and see if that helps things out.

Your issue may or may not go away with a new interface.  Blue screens are  more related to your computer system and not normally a thing an audio driver would be involved with.  
Quad Captures , unless defective which is possible, are given a high rating from happy owners. 
I just read a thread on GearSlutz where someone said they had owned a U22 a Scarlett 2i4 and now a Quad Capture and said it was the best of the bunch for them. 
 
You don't give us your system specs so please post that as well. 
 
Download and run Latency Mon as well when trouble shooting it's good to know what running.

I use the Quad Capture without any problems. I have it as my only audio device and make sure that all other drivers are disconnected, including the audio drivers from my video card. All apps use this device and I use the machine for everything. In Sonar preferences I make sure that the option to share the audio driver is not checked.

Same as me.
Quad capture as on only device on my PC, any other audio drivers disabled.
I use ASIO drivers.
Never had any issues.

You can read blue screen crashes and it will tell you exactly what is causing it. I bet every crash is for the same thing.
