Hi - whenever I save anything to my desktop (photos, new folders, program shortcuts etc), the next time I turn the computer on these icons have changed into a playing card, the ace of spades, to be precise! Refreshing the desktop always puts them back to normal, but as soon as I go away from the desktop and then return to it, there they all are again!

It's not a major problem, but it is really starting to irritate me - also, I don't know why it's the ace of spades; I can't think of a single program that the image could have come from. And it is just a change in the icon, on mouseover the computer knows exactly what's being hidden underneath.

Any ideas would be greatly appreciated

Please, the next time this happens hit the print screen button, open up paint, and then hit control + v to paste. Upload the file here for us to analyze.
