Creative Sound Blaster 16 Plug and Play...HELP

Recommended by Wim's BIOS...

I have a fairly old computer, but I just swapped the motherboard and and the CPU with a little quicker one. But the new motherboard has a 'Creative Sound Blaster 16' onboard sound card, but It don't work properly. It will play very slow from Windows Media Player, but doesn't play anything else. It gets 'stuck' and just keeps repeating the same note, so therefore you have to shut down, then restart to get rid of it. I do a lot of work with audio mixing, and need at least a sound card. (Obviously!)
I have set the acceleration level back and forth and it doesn't make a difference. I have also tried to look for drivers, but the lastest I could find were 1999 drivers. I have even formatted my computer and installed everything from scratch, but still no difference. The system says that everything is working properly too. I don't know what else to do.... Can someone please help???

Check for IRQ conflict.

Done. No conflicts of any sort.

Did you format and reinstall after the motherboard swap?

hmm, something is crawling from under some dust in the back of my mind...

What motherboard do you have and which Creative chip is used on that?

It don't matter anymore. I got it all sort out. Thanx for the help anyway. Its a VIA 82C597 rev 4 running a Cyrix 6x86 -333MX CPU. I Dissabled the onboard USB IRQ, and is running fine now.
Thanx.
