Most my games start stuttering after a few minutes then crash to desktop with no error message. I looked in event viewer, and it says "device attached to system is not functioning". I was using a wired Xbox controller. I unplugged it, and plugged it back in to the USB port. I also switched to another USB port. I also have my headphones plugged, and did the same, but my games keep crashing. What do you think is going on?
