If you recently updated audio drivers, try rolling back. If you updated from the Device Manger, try going directly to the manufacturer (Don't use 3rd party) site. Now it depends on your comfort level. If you have some computer skills go into the bios and turn High Precision Event Timer (HPET) off. Try finding it in Power Management, but it might be anywhere in the bios. If that doesn't help, reset back to original. I'm assuming you already ran PC Health and sfc /scannow.
