Audio Adapter ATI SB200 - AC'97 Audio Controller
Audio Adapter C-Media CMI8738/C3DX Audio Device
This is your on board sound.
If the card is installed correctly it should be in Add Remove Programs. The drivers need to be cleaned out. Get some CCleaner and under uninstall find anything that is soundcard related...the drivers should show up. They should also be in your program files. Do a search find them and delete as necessary. Now your card will need to be reinstalled but before you do that.......get rid of onboard sound. The PCI sound card can sit in the computer and wait.
FOR ONBOARD SOUND: Make sure it isn't in Device Manager, if it is DISABLE IT, after you are 100% on that. Go into Bio's under Integrated Perphials there should be AC97 AUDIO set to AUTO. If you havent disabled it do so now. Now your on board sound will not work.
Then your card should work with all proper plugs drivers ect. Your computer should recognize it automaticly and take you through all the steps. Follow and Download everything off of CD installation disk and Blamo it should work
Well hopefully. I didn't read the whole thread but maybe that helps a little.
