MEDAL WEBSITE IS MAKING MY PC BAD

so ive had my pc restart automatically twice today, and its a bit of a far reach but i believe its because of medal because it happened both times when it was on their website, when my pc turns on after the automatic restart, my headphones are recognized at all, i put it in both headphone jack slots and it doesnt recognize, the first time i fixed it by moving things around in the playback section in sound settings, but now i cant find a fix. please help
