So my problem began while playing a game. I was playing and all of a sudden the sound cut out. I could not figure out why, and after a few minutes I realized my mouse was not working either. My computer is using an Ibuypower tower and it contains two separate areas for USB ports. One of them contained both my mouse and my USB headset. The other area (which has two ports) works perfectly fine. This back area has both USB 3.0 and 2.0 ports (2 of each, so 4 altogether). I went into my playback devices (windows 10) and saw that it said they were all not plugged in, as shown in the attached photo. I have no idea what happened and I'm not very good with computers. I went into my tower to see if it was a loose cord or something and quickly realized I was in over my head. I'm hoping it's something that can be fixed without having to take it into a repair shop, but if it is please tell me. All help is appreciated.
