I think I should give more info after today's hard work on it.

In system information, it shows no conflict and DMA problem (in fact it
didn't show ANY problem at all), but in device manager, it says the sound
card couldn't find any free DMA. there are free DMAs shown in system
information.

I finaly changed the sound card DMA config (every hard to do so), now
everything back to work again. What I don't understand is how and why the
only one DMA problem distroyed whole system. I have some questions here:
1) if change sound card config would solve the problem, why change SCSI
config wouldn't?
2) If only the sound card has problem, why Display (for games) and TV
capture cards also stopped working?
3) As I said, in system information, it shows free DMAs and no problem, why
device manager says no free DMA?

Hope someone can help me with those questions. TIA
