Idisabled the onboard in the Bios.
Restarted but then got a BSOD after about 5 minutes.
So i have just removed (Physicaly) the XFi card and re enabled the Onboard.
Any chance you can check the attached dump file to see if it is still same Sound card as before.
Also How do you work out what the problem is from the Dump file.
That way i wont have to bother you in future
