Problem with sound after cutting off the light.

All Dorough! Faced not clear problem, yesterday turned off the lights, crank up the computer today, stopped working sound when turn the headset on, says that no audio devices, it is necessary only to disconnect the headphones, writes that they were connected, (yeah, despite the fact that all devices are at this time disabled). In General, the bizarre, sin to defective sound card, or maybe it's because of another fucking update vin10. External damage is not noticed, firewood, tried to reinstall - no use. Anyone faced with?
