Hi, the sound seems to be from the speakers but cant be 100% sure.
Windows does freeze while the sound is happening, what used to happen was the laptop completely crashed and a kernel error came up, and i would have to completely reboot windows again from scratch losing all my files etc, when the sound happens now i just hold my finger down on the power off button and i can restart windows normally, but since i have updated all my drivers, icreased my RAM and added regcure, things seem to be a bit bette,r but the sound still happens just when i play music or videos. the sound driver i have now is conexant high definition audio.
Regards
steven
