While playing a game on my laptop (Lenovo IdeaPad) the game crashed and the screen went black. I eventually had to hold the power button and turn it off. When I turned it back on the mouse was not working. I realized nothing worked in either of the USB 3.0 slots or the one USB 2.0 slot. I can use the touchpad, but hate that. I uninstalled the drivers for the USB ports/hubs and updated the BIOS and nothing has fixed the issue. If I try to install the USB driver it says it is the same version and can't update. Any ideas?
