We had multiple problems with the OS and partitions, so we reinstalled Windows XP on the Sony desktop (it previously had XP on it). After install I went to the Sony website and downloaded all of the driver packages and installed them. Now the Audio and USB do not work. Very strange is that a Lexar flash drive will work, but PNY and Memorex flash drives and printers will not work--it does not recognize them as being installed because it says that it needs to locate drivers. When I point back to the Sony drivers (or the printers' drivers) they will hang for a few minutes and then fail. Any suggestions on this? I have also updated the BIOS per the update on Sony's website.
