Q: There are randomly coloured pixels appearing on my MacBook Pro LED when I attempt to open or preview a media file.  Is this the graphics card?

I recently had to switch out the hard drive on my Early 2011 13" MacBook Pro.  When I got the computer back from the Apple Store I began loading my old content onto the machine.  When previewing and opening files, they would appear with randomly coloured splotches of pixels on them.    This continues to happen when browsing folders on my machine.

 

The files do not show up with splotches on other computers, and are not in the same places each time I open the file, which leads me to believe they are problems with my machine and not the files themselves.

 

I hypothesise this is the graphics card, but I don't know enough about the hardware to know for sure.  Any help would be greatly appreciated.

 

See examples below.

    To follow-up.  The problem has gotten worse, as it not only displays glitches during file previews, but imprints glitches on exported files.  No good.

     

    There are many issues popping up now related to 15" and 17" MacBook Pros from 2011, and I wonder if this is a related issue.   In either case, I would love a response from someone at Apple about this issue.
