UA-1G soundcard and Sonar X1d problems

Hi there i have a problem since i installed my new computer.
I bought a new computer with lots of ram and new videocards in it.
On my old pc i could make songs in Sonar X1 and the UA-1G soundcard from cakewalk.
But now there is a problem, after say a few min. there appears a pop up screen in Sonar and i cann''t make music anymore until i restart the pc and then i can work for a couple of min.
 
The message is like : The AudioEngine stoped because the soundcard is in use by another application.
But there is no other application running !!! I only have a few vst plugins running like Kontakt or Waves plugins.
 
What can be wrong ???
My pc is Windows 7 64 Bits running only 64 bits software and the drivers of the UA-1G soundcard is 64bits aswell.
Is this soundcard not good anymore for my quadcore pc running 2x1 Gb videocards and 8 gigs of ram?
 
Please help needed not to difficult english because i live in the netherlands and my english isn't that good ;)
 
Thanx in advance

Thanx

One thing to check that might help avoid any further problems.... is Windows using the UA-1G as the Default Playback Device? If yes, I suggest using your onboard audio chip, or soundcard, for Windows sounds. That way Windows won't try to use the audio device at the same time Sonar is. If you want to use the UA-1G for Windows audio playback, then you can select the No Sounds soundscheme.
