As stated in the title, all of a sudden my laptop (less than a year old) will no longer register any devices plugged into either of the USB ports or the headphone jack. I have tried both of my headsets and both of my mouses but it won't register anything. I've tried restarting my computer but that didn't help. Any advice would be much appreciated as I do not know much about computers. My laptop is the Acer Nitro 5 Gaming Laptop if that is at all helpful.
