Faulty Fujifilm f50 fd PLEASE HELP!

My Fujifilm f50 fd is not working properly.

When I take pictures everything seems to work ok. I can view the images on the LED screen on the camera.

But when I load them on to my computer the first 100 or so pictures are alright, but the rest are corrupt.

The last time it happened the first images were ok then some were corrupt and the last few were fine.

I've tried a couple of media cards but the same thing happens.

The camera has ran out of warranty so any advice and thoughts would be greatly welcomed.

I'm really gutted cos we've just had a new baby and have lost some really special photos.
