Video card/monitor ghosting
So, I am having a rather strange issue where I get ghosting on my monitor - it's the best way I can describe it! It happens to Finder windows, open programs, etc. What you see in the photo attached to this post is a bunch of shortcuts/icons from the desktop which I moved into a different folder.
When this happens, usually the 'ghost' stays on the monitor for a few minutes, and then just disappears.
Any thoughts on what may be happening? Thanks in advance!

P.S. Please ignore the slightly dirty monitor...:o
