From being all fine random rawfiles suddenly gets corrupted. I have tried to open them both in LR CC and PS CC The files appears normal in windows/Faststone, but in LR and PS they are damaged. What can I do about this? What is happening here?

Hi Aachel,
It seems to be an issue with the Graphics Card on the computer, I would suggest you to please update the Graphic Card drivers on the computer.
And then reimport the images in Lightroom.

Faststone and the Windows viewer are displaying the embedded JPEG preview. What you are seeing is an indication that you have a hardware problem somewhere in your system. It could be a failing hard drive, a failing camera card, a bad USB cable if you are using one. It's a problem that you are going to have to isolate.
