MacBook Pro 2009, Extreme Heat from VLC
When I watch something in VLC or download via uTorrent on my MacBook Pro (see inserted pix below), it quickly heats up to 95 degrees and becomes really slow in performance - almost to the point I can't shut it down or restart the "right" way.
I replaced my first hard drive, which crashed, about two years ago, if that has anything to do with it. My battery status is currently at "Service Battery", so I gotta get that fixed - but is that the reason for this behaviour? I think this overheating issue started way later than the battery started struggling.
I don't know. I'm definitely not an expert at computers and I would really appreciate a decent, but simple, breakdown on what could be wrong and what I should or could do. Other forums really don't mention a solution, just rambling on about the facts.
Maybe I should mention that I can watch movie-files with QuickTime with no problem whatsoever.
