GeForce 2 MX interfering with sound card?

[Guest]

Has anyone seen the following problem before? It's driving me nuts:

I have just replaced my SiS 6326 video card with a new GeForce 2 MX 64 (from Cardex). Since then I get noise/crackle on my audio output. My audio card is a Crystal CS 4281. There was absolutely no 'noise' when using the SiS and the problem definitely started once I had installed the GeForce 2.

The problem occurs in certain circumstances only; when I'm playing SimCity 3K there is no crackle during the opening 'splash' animation, but it affects the background music prior to starting the game and thereafter; when I'm playing Black & White it affects the voices of the consciences (and others) but not the background sounds; the basic background sounds in Windows aren't affected.

My base system is a K6-III+500 in a TMC TI5VGF. The CS 4281 is the only PCI card installed and the system has no ISA slots at all. I have a modem and scanner on USB.

I've tried re-installing everything (in different orders) without success so far. Does anyone know what might be occurring?

Regards,
NJD.

Nothing to do with it, bad motherboard shielding. Only replacing mobo/sndcard/videocard may help.
