I was trying to install a Windows 8 Pro upgrade when part way through it told me I had to remove some incompatible drivers before installation could continue. I figured Windows knew what it was doing so uninstalled them. I uninstalled the first one before noting what it was. Then I uninstalled the second one. But though afterward that doesn't sound right "it was Intel USB 3.0 Extensible Host Contoller Driver". Oh, Oh !! Anyway now I have no mouse or keyboard so have no input capability to reinstall ? Help, how can I rectify this ? My board is a GA-Z77X-UD5H. Would resetting the BIOS do anything ? And If so how do I do that ? Really appreciate any help ! [email protected]
