Working solution!! One of Barbara-Bookworm's earlier replies in the Archive told the user to go to Control Panel, find the Yellow ! ? beside audio or video and R-Click to uninstall. I would recommend one at a time. Reboot the computer and Windows XP will find the Hardware and install. I did this and it worked for my onboard video card. Failed for the audio card on the first try. I went to BIOS and found that the onboard sound or audio card was a VIA-3058 AC97 (Info is hidden in BIOS sub-menus) . Again, I read Barbara's advice and downloaded the Realtek driver (Realtek
http://www.realtek.com.tw/downloads/...&GetDown=false). First I uninstalled the Multimedia Audio Controller with a R-click in Control Panel, then rebooted and when WinXP found the new hardware, I chose "Pick from List". It gave me four choices. I chose the VIA and AC97 and installed. After that install, when there were no errors in Control Panel but still no sound, I ran the downloaded EXE from Realtek. I have VIDEO AND AUDIO. Thanks Barbara!
NOTE: ? ! Multimedia Audio Controller and ? ! Video Controller (VGA Compatible) means the computer has no idea what to try and install. It sees "something" but doesn't know what. If WinXP can't detect during a "New Hardware Found" routine, then you have to tell the computer what you have and pick from a list.
