Hey guys, i badly need help. I've got HP Notebook - 14-ac136tu here. Before it was on windows10 and i reformatted it to windows7 due to the owner's choice. So i installed few drivers at first, along with other apps and i installed bluetooth, wifi, other chipsets later. After those drivers (latter) were installed, few minutes later, "usb not recognized" pops up and then screen freezes after few seconds. What should i do? Please, heeeelp :) I'll be so thankful for your answers!
