Weird issue in daw with 11r !

[san]

Hi guys !
A problem appeared 2 days ago with my 11r.
In my daw, (live 8), while i m playing a song, after few minutes the sound shutdown or stops, no sound comes from the daw anymore.
If i play guitar, it s ok , sound comes, if i play a mp3 with media player, it s ok.
But no more in the daw. Rrrrr and the eleven rack becomes like undetect for the daw and sound artefacts come if I turn the volume knob.

I try with 2 computers , same problem happened ! I have another sound card. No problem it works!

If i restart the daw , it will work, for fews minutes and then same crashing again.

Have you already met this kind of problem?

Thank you for any kind of help
