Dell Optiplex 780
service pack 3
4 GB memory
Dual core processor 64 bit ready

After 4 years the computer crashed. I formatted the hard drive and reinstalled XP. I went to Dells site and tried downloading drivers for the computer and to Intel's site. All was installed except for
"Other Devices". These are
"audio device on high definition audio bus"
"OTG102"
"OTG102"
"PCI Serial Port"
"Video Controller"
"Video Controller (VGA Compatible)"

Any help would be appreciated.

Thanks
