SD card problema

[PritishRaje]

I transferred images from my camera SD card to laptop as my PC wasn't in a good condition.Now I took those images in a pd and inserted it in my pc and I cannot view the images .
Windows photo viewer says : File not supported or too big.
picasa says : invalid

Now when I insert same pd again in theblaptop...I can view all inages

You say your PC "wasn't in good condition" so if that's still the case it could be the cause of the problem, especially since there's nothing wrong with the pen drive because it still works perfectly well in your laptop.
