Recently whenever I'm playing games, all of my USB ports would just randomly shut off. Anything I have plugged into the ports, front and back, would just stop working, where I then have to restart my computer to get them working again. I'm running 8.1 and when I play games, the computer is at its hottest. My computer used to run fine with the heat. So is the constant heat finally getting to the motherboard, or is it just some bad update with 8.1?
