So I've been using the 2 top ports for my mouse and keyboard which seemed to work without any problems for a couple days and now it's the top 2 + front 2 that doesn't work and the 4 ports in the back work fine. Does anybody have any idea what could be the problem and if there is any solution to this? I'm just afraid all 8 usb ports will die on me which will make it impossible for me to do anything since this pc only has usb ports for the mouse/keyboard
