I have a Dell E5500 running Windows 7 and the keyboard and mouse stopped working. For the keyboard I get "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)". For the mouse I get "This device cannot start. (Code 10)".
I have tried deleting/re-installing devices and drivers, ran AVG & Malwarebytes programs, disk check, verified and updated bios, deleted all windows updates since problem, verified all programs are enabled in MSCONFIG.
I do have this machine running both Windows XP and 7 as a dual boot. WIndows XP works just fine. I cannot get the devices to work in safe mode. I believe that there is a registry issue but of coarse I have no backup.
Any help would be appreciated before I have to reload the machine.
