Sometimes my computer displays splotches of grey or white on something meant to be black.

In working on a website, I noticed some of the jpgs had bits of white scattered throughout something that was actually black--e.g. reflections on a pond, shadows, someone's hair. At first I thought it was a Firefox bug, but trying it in IE showed the same thing. Viewing it on a different computer didn't. Opening the images in Irfanview did, but moving the program around the screen changed what those places displayed as, based on what was in the program *behind* it: black over dark objects, grey over text, white over a white background.
Rebooting the computer made the problem stop, but I've (unintentionally) reproduced it twice now. Both times it seems to have been caused by leaving the DVD player open and paused for a long time (e.g. long enough to go cook, eat, and wash the dishes).
I tried taking screenshots, but opening them after a reboot shows them to be perfectly normal.
So ... obviously to avoid the problem I should not leave the DVD player open and paused for a long time. But what's going on? Is it a driver problem? Incorrect monitor profile? Something relatively harmless, or should I expect my video card and/or RAM to fail soon?
Sorry if this has been answered before; I've missed it if so (and had no look at the altar of Google).
