A few more details are needed: Is this a continuation of a previous thread (you say "still" a couple of times)?
If it isn't, when did your sound card stop working? What Windows version are you on now? What are your basic PC specs?
At first glance, it is unlikely that just using a different Windows, as you seem to be suggesting, will cure your problem. But fill us in on the details and someone should be able to sort it out.
