Do you know what happened to my computer?

[LSS10095]

I sometimes get the following BSoD:

STOP:0x000000D1(0x00000000, 0x00000002, 0x00000000, 0xF79FAC73)

What happened?

Here are the minidumps, please help me find it out.

All of the minidumps point to ALCXWDM.SYS which is an audio device driver. Try updating your audio device drivers.
