Everything is in the title. I work on PC (Win 7);4 cores processor AMD Phenom; 16 Go; 3 HDD . Does anybody experience the same problem? (no antivirus installed; nothing just music softwares). Thanks for any help!

Can you please provide additional detail as to what you are doing in Sonar when these crashes occur?
 
Also, are you running X2, or X2a?
 
Windows 64-bit?  And is your Windows 7 up to date with maintenance?
 
What driver version, exactly, are you using for your audio interface?
 
What driver mode in Sonar are you using?
 
What is the Sample Rate and ASIO Buffer Size settings values in your Interface?
 
What Sample Rate and Record Bit-Depth are you using in Sonar?
 
Does this happen in particular projects?  Only sepecific ones?  Can you make it crash at the same point in time?
 
Are you running 32-bit or 64-bit Sonar?
 
If running 64-bit Sonar, please list all of the names of plugins present in one of the projects where it crashes?
 
Sorry for all of the questions - there are a lot of things to look at.  Answering all of the above should be pretty quick and painless - short answers really.
 
Thanks - I will do my best to help figure out what is happening.

Have you read the section in the Quad Capture manual that explains how to improve the performance? Sonar's Reference Guide has a similar chapter IIRC.

No issues for me - my spec in the signature. Quadcapture connected by USB2
Have you got the latest Quadcapture drivers?
64 or 32 bit?
Connected to USB2 or USB3 port? - USB3 can be problematic apparently.

Thanks a lot guys! I'll answer all your questions. I will have no internet for about 1 week, so as soon as I can reach internet again, I'll come back with the answers. Thanks!!
