i have a toshiba L505d-s5695 laptop that had a video card go bad. I replaced the MB with another bought on line. After i installed, the computer turned on with video, booted to the windows sign on screen. At that time i realized that the keyboard/touch pad and all the USB ports were not working. Turned computer off, restarted and the system repair screen came on and requested that i system restore, which i cant because keyboard/touch pad dont work. Externals of both wont work because USB's dont work.I removed MB and checked all my connections and all was well. Is this a malfunction in the MB, or is there something else at play? Thanks in advance for any help.....
