E6440 - entry point error when installing drivers

Trying to reinstall Windows 7 pro 64bit on an E6440 that had a failed hard drive.  New SSD installed, original Windows 7 Pro DVD used to reinstall.  Installation went fine.  However, whenever I try to install any of the Dell drivers, I get the following error:

"The procedure entry point AddDllDirectory could not be located in the dynamic link library KERNAL32.dll"

I get this error no matter which driver I try - chipset, video, sata, network, whatever.  I can't get a single Dell driver to install.

Here's what I have tried so far.

1.  Wiped drive and reinstalled Windows from scratch.  Same result.

2. Downloaded SP1 from microsoft (from a working computer) and installed on the E6440.  Installed without a problem.  Still getting the entry point error.

3.  Tried running SFC /scannow.  Found no errors.

4.  Tried booting off Windows install DVD, then running SFC /scannow using the installation media for reference.  Found no errors.

5. Ran chkdsk /f.  Found no errors.

6. Ran Dell diagnostics that is built in to the BIOS.  Found no errors.

I've been working on computers for a long time and have not come across something like this.  Because I can't get any drivers to install, I can't get any internet on the E6440, so I can't run any of the Dell online diagnostics.  I'm out of ideas.

Does anyone have an idea?

Thanks
