Thanks a lot stevty2889 that link was a big help.    Yes, I looked over the HP site for the drivers, and no there were no disks that came with the computer.   I had to format the drive and delete the patitions because of a virus.   But now the Ethernet (on-board) and the sound (on-board) devices are not detected.   I believe from the link you should me that the sound is AC97 and nVidia Drivers should solve that.  I will attempt that when I get home today.  
Any other thoughts?
I just can't believe that HP would send a system out that by default Windows XP does not recognize the devices on, and then not include the device drivers on a seperate disk.   
I have contacted HP, but as of yet no reply.
Thanks again for your help.   Any futher assistance would be  greatly appreciated!
