Which sound card drivers do you use exactly? Check this in device manager: Highlight the sound card, click on "Properties" ad go to the sheet "Drivers". Is there the abbreviation "(WDM)" near any of the components? If yes, try to get updated drivers from our DLL page, or Aztech's web site:

Also check Windows Update site.

: On a Asus P2V celeron 400 system my Aztech PCI 338-A3D sound card often crashes the system when an application is using it, or even when desktop themes are running in the background. One of its components is using IRQ 9 which I thought might be a problem but when I manually change the settings and reboot, I get a problem with IFSMGR.vxd and have to run Win98 under 'Safe Setting' and re-enable autoconfiguring of IRQ's, I/O's etc. Any help would be appreciated.
