I've had my 10D for about two months now, and I've noticed random colored pixels (interference) in some of my pictures but not all. The problem is not with the camera, the problem is with my computer. When I connect the camera to my TV via the supplied cord the pixels do not show up, but if I download them to the PC they show up, sometimes. I have tried to download the pictures to another computer and I had no problems. I have tried all of the USB ports on my PC and I still get the pixels. Can anyone suggest anything to help, Has anyone else had this problem? I am just using Windows XP as a viewer, but it show up on photoshop and everything. It also shows up in the print if I print the picture out.
Try uploading your photos with a compact flash reader instead of the camera. They're cheap and I prefer getting my photos that way instead of using the camera. Or maybe you need a new monitor?
I don't know if this is the problem or not but I bumped into something similar when showing people this site. Some people have their computers set to 1024x768 resolution do not have the video driver set to "true color". This had caused weird mappings of the color maps causing some strange effects including strange color pixels (not sure why). Try START>Settings>Control Panel>Display>Settings to make sure you are using 24 or 32 Bit True Color rather than the 16 bit High Color.
It must be occurring during the transfer to your computer. It clearly isn't the monitor or display settings or software, especially since you say it shows up on the prints. It isn't the card because it does fine with other computers, unless your puter doesn't like this particular card.
I would first try what paganini suggested. If that doesn't work then I'm at a loss for advice other than rebuild your computer, but I wouldn't do that unless I lost all hope for a solution.
What type of pictures do you see the random pixels on? Is it by any chance on long exposures on solid background? I see this type of thing on my D100 with long exposures on black background. The D100 has a "long exposure noise reduction" mode that cleans that up.
I favor this explanation since you see it on the monitor and the print. You would not see it on the TV because the TV is such low resolution and is interlaced.
The picture that this happens on are just normal exposures. Light areas, dark areas, it doesn't really seem to matter. The ISO speed can be set anywhere form 100 to 1600 and it happens on them all. It's not the card either, I have a 1 Gig microdrive that it happens on and a 256 Mb card that it happens on.
REMEMBER, the scans you see on your TV are not nearly the same as what you see on your PC Monitor.(you don't see each pixel on your tv) It is most likely your camera. The card reader is good advise too. Usually much faster than using your camera and less wear on the expensive stuff.
Do you see them at ALL quality settings? or just on raw?
I've tried the camera on two other computers and I had no problems with spots. The problem must be with the computer. I don't know how to post a screen shot of the pictures.

To take a screenshot:
1. Load the image into a program where you can clearly see these spots.
2. Hit the "Print Scrn" button on your keyboard (this places the screenshot in your clipboard)
3. Open a new document in your photo editing software and edit>paste
4. Save the image and upload it somewhere on the net and give us the link.
Guys I finally found out what was causing the problem with the pixels.
It wasn't the camera at all, It was the RAM in my computer. It appears that I had a bad stick of ram in my PC and that was causing the trouble.
