Thank you, Bill, for your response. After pursuing the issue further (and according to your suggestion), it is evident that the problem has been located in the device manager. The six hardware items listed there all have a yellow exclamation mark next to them.
When I purchased the computer from Dell t was accompanied by a recovery CD (XP Pro OS), a User Documentation CD for the monitor, and a Drivers and Utilities CD. After the reformat of the hard drive, the three (3) foregoing CD's were reloaded. But in the device manager the six (6) yellow exclamation marks still were displayed.
Dell is sending me the the drivers I need (at no charge)
. Actually, the only drivers on the Drivers and Utilities CD were primarily for a wireless adapter. So, ideally, once I receive the necessary drivers we will be up and running again. If not, I'll seek your assistance again.
Regards,
John
