I have a new Lenovo T530. At semi-random times, the device disconnect sound will play twice, the keyboard and mouse will become unresponsive and the internet (wired, not wifi) will disconnect. Video and sound continue working normally. The only fix is a hard reboot. This seems to happen most often at times when the processor is being taxed (e.g. starting a game, working in photoshop), though it has happened while just watching netflix. The computer can work normally for several days between crashes; other times it will crash three times within a few hours. I've attached a Speccy system snapshot. Any input is appreciated. Thank you.
