Simply opening images in Lightroom should not corrupt them because Lightroom itself doesn't make any changes to the images. Can you provide a screenshot of one of the images so that we can see the problem you are experiencing?
It is likely not the graphics card.
It is more likely some piece of hardware in the transmission of the photo from camera card to computer (camera card, card reader or USB cable/USB port, hard disk) or the computer memory.
I'm having the exact same problem on my MacBook Pro which is only a few months old:
I can't see this being a hardware issue as its an SSD and the RAW Files don't show up like this. i've tried increasing the Cache and deleting to old one so it has to load a new one but still no luck. Running out of patience with this software as is beginning to cost on lost editing time
It's always a hardware problem. Your files have been corrupted in the transmission to the computer from the camera or on the hard disk/SSD or memory. You need to try using different hardware to isolate the bad component.
If i use the same RAW file in Aperture, it shows as it should
Do you actually edit the photo in Aperture or just look at the thumbnail? The thumbnail is created from the Jpg preview and is often uncorrupted when the actual raw image is corrupted.
Also, Lightroom never writes to your raw files, so it is impossible for Lightroom to cause corruption. Lightroom only reads from the disk, so if it shows you a corrupted image, it's because the disk sent Lightroom a corrupted image.
i used to use Apertue, but tried Lightroom and preferred that.
i edit and then add a logo as i work in a nightclub. the album before this one worked fine which came off the same memory card, but in a separate folder from the night before. i managed to get through editing them all until it come exporting all the photos and then i began to do it
I went back to Photoshop CC2014 to check on the bad images in LR5. What I
found is that the original image is fine but there is no records of
8566-2-2.CR2 in my hard folder on disk. The image 8566.CR2 is there. I'm
really confused by all this. It does appear to be a Lightroom issue but I
don't know why. It does it sometimes but not all the time. I just
downloaded a shoot from today. I was nervous about bringing the images in
in LR but I did use a card reader instead of the onboard reader on my PC.
Now not sure if the onboard reader may be causing the problem. I just
didn't want to lose these images so tried the portable card reader.

This is ABSOLUTELY an untrue statement. I have time and time again in the past year or so seen instances (and it happens all the time now) where I import files fine, they preview fine, I make adjustments, I export them, I work on them again the next day, and then eventually I come back to do something a few days later with them again and the instant I click on one to view it.....THEN it shows that big corrupted view.
The ONLY way around this short-term is to delete the file from your library, then re-import it, then reapply the changes.
HUGE HUGE HUGE HUGE HUGE waste of my time right now and for every person that say it is hardware related I can dispute every single instance of that across the board with proof of how I've tested it.
ADOBE I NEED AN ANSWER, NOT A FORUM WHERE NO ONE HELPS ME.

Have you actually tested the computer memory to see if it is malfunctioning or not?
Have you actually run diagnostics on your hard disk to see if there are bad sectors?
