Hi Kirk. Hi Ron.
According to Dell it seems the original onboard audio was Creative Labs Sound Blaster.

These are the instructions for removing old ATI software. Is this the method you used?
Removing Old ATI Software
- Click on Start, then Control Panel, then go to Add/Remove Programs.
- At the top of the list you should see several ATI entries. Select the entry entitled ATI Software Uninstall Utility, and click Change/Remove.
- You will be prompted to restart your system once the uninstall is complete.
- Once restarted, check the Add/Remove Programs list again for any remaining ATI software.
- If any ATI software is still listed, click Change/Remove on those entries to uninstall each one individually.
- Next, please scroll through the list until you find an entry called DAO.
- Select DAO, then Click Change/Remove to uninstall this program.
Is this the Raedeon HD 2600 series? It looks like there might be newer drivers. Catalyst and just the display drivers alone.
However first things first as AdvancedSetup said. Get the system back to normal first then start fresh.
