Hi Harvey W.,
Windows 7 drivers aren’t available for your Dell computer (Dell Inspiron 530s), yet. Hence Conexant D850 56k V9.0 modem drivers for Windows 7 aren’t available, too.
However, what you could do as an alternative would be to download and install the Windows Vista drivers in Windows Vista compatibility mode in Windows 7 and check if that fixes the issue.
You may download and install the Windows Vista drivers from the link below:
Note: If you’re using 64-bit version, select Windows Vista 64-bit from the Operating System drop-down list.
Uninstall the modem drivers from the computer before installing the same in Vista compatibility mode.
William p young chata ebookers. US District Court, Central District of California. Retrieved 30 July 2011.
To install drivers in Vista Compatibility mode,
1. Right-click the installation file and select Properties.
2. Click the Compatibility tab.
3. Under Compatibility mode, check the Run this program in compatibility mode for: option.

4. Select either Windows Vista (Service Pack 1) or Windows Vista (Service Pack 2) from the available options.
5. Click Apply and OK.
Refer the link below for more information on compatibility mode:
Make older programs run in this version of Windows
If the steps mentioned above do not help in fixing the issue, I’d recommend you to contact Dell Support for further assistance:

Hope this information helps.
