ThinkPad T420 clicking noise when watching video.
Yeah, so I'm running Slackware, and every time I watch a video file on my laptop, there is a feint clicking noise coming from the right hand side of my computer. Strangely, the larger the window, the slightly louder it gets :S
Any ideas? Anything to worry about do you think?
Btw I have the Intel Integrated HD video card.
