All USB ports lost, HELP
I posted this request in the only thread I could find on this problem, but
nobody reponed, So I am trying here in a new request. Thursday afternoon, my computer suddenly issued a series of USB port unplugging sounds. Investigation has revealed that none of the USB ports on my machine are functioning. No USB printer, keyboard or mouse (without PS/2). There were five windows displayed with the following message: "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." Occasionally when I try to plug in a device, while no plugging sound is issued, the malfunction message will be displayed. I have gone to the earliest restore point and that did not work. I have un-installed all USB drivers in Device Manager and after Windows re-installed them the Devices still do not work. Windows only returns the malfunction message when plugged in. Help, I have no clue as to what happened here. |
