I have been having severe HD problems and will be replacing. I have coaxed it back to some degree but have USB problems as all USB Root hubs show yellow triangle and Error 39. Rest of USB Host controllers show "working properly". I have my mouse and keyboard working through PS/2 ports now, so have some control. Should I just uninstall each Root and reboot or what? I want to get enough working so that I can copy files from old to new HD, if possible. Thanks
