OK My problems have been resolved. I had reinstalled the chipset drivers and the DSS twice to no avail for the usb problem. As for the sound drivers, I located a disk for the Sound Blaster card. I had forgotten that this card was in the system. It is not a gaming or entertainment machine. Installing the software took care of the audio problem The usb problem remained. I was able to install an Epson scanner.  But storage devices would not function until I left them connected and updated the drivers. It was also necessary to turn off all virus scanning. But since this was necessary for all software that I have installed, I can't believe that I overlooked this all the times I tried to resolve this problem. Any way 3rd times a charm. Thanks for the help
Hi:  I recently reinstalled the OS on my Dell 390 Precision workstation. Windows XP SP3. The win login was corrupted and no amount of coaxing could get me in. The two disk drives C & D, for OS and data files respectively, are OK ; checked using SpinRite v6.0. Everything from drive C that was needed was backed up. Two repair installations did not work but a complete installation of the OS from the Dell re-installation CD was successful. After installing all of the drivers in the recommended sequence, two problems remain, the audio system does not work and external usb devices are not recognized by the system. All of the usb ports appear to be active, since the keyboard and mouse function no matter which ports I use, but usb memory sticks or external hard drives are not recognized by the system. There is no indication that the system recognizes the new hardware. I just plugged in my Wacom pen tablet, it was recognized and functions, but memory devices still don't work. What should I do next? Does anyone have any suggestions on how I should proceed now?  Thanks
No USB support for external storage and no audio capability
