I have a Toshiba Satellite A665-S5170 and since I have purchased this laptop in May of 2011 I have been getting glitching noises everytime I move my laptop. I understand the HDD Protection is on but the laptop still makes glitching sounds when playing audio alone or watching a video on YouTube without touching the laptop. Also Listening to music while downloading or doing something on the laptop. I turned off the HDD Protection and it's still the same. Is there something I can do to prevent this from happening? Please help I know my computer is clean from viruses because I just wiped it 2 weeks ago and I run virus scan periodically.
