Ok...This is what I know:
I'm running Vista and am having a very serious problem with (what appear to be) corrupted picture files, both jpeg and .cr2. Random pics will just appear to fall apart on the thumb nail and in full viewing. The problem is system wide, it doesn't matter what method i use to view the images the result is the same. I use ACDSee pro 2, LightRoom 2, Windows Explorer and Canon Digital Photo Professional. All the programs see the same weird lines. ACDSee will give me a brief glimps of the photo then revert back to the messed up view.
Now, I sent two of the photos to a friend of mine to check on his system and to my suprise they where fine. He was able to view them, make a tiff and send them back to me with no problem. So, it is obvious that the files are not corrupt and this is a problem with my system. My friend said it may be some kind of problem with my video card, but he was only guessing.
My computer is only 3 months old and has already fatally crashed once. The files on my back up exteranl drive view excatly the same way. I use Sync Toy to do my back ups.
Hope this is enough info for someone to help me. If you need more just ask. I really need this to not happen anymore. I'm a pro photographer and this could potentially cost me thousands of dollars in lost work.
I tried uploading an example but i was told it was missing a security token.
Thanks a bunch
