Hello all, im having big problem and its really frustrating, when i want to download something at full speed, all my USB ports turn off, then i must restart pc on the case button. Even when im not downloading, when im surfing its gets off automatically. I checked all setting and its all ok, in power options Selective suspend is off. In device manager, all usb ports via Human interface devices and Universal Serial Bus controllers "allow the computer to turn off this device to save power", all boxes are off. What can i else try? Is it a OS problem or hardware problem? im on windows 10
