Great Whiteout of Doom

[hildy89]

Okay, this is getting annoying. Every once in awhile, I keep getting this moment where my monitor suddenly turns completely white and locks up. It eventually goes back to normal, but I'd like to find out what's causing this creature. I've run the virus and spybot software to make sure it isn't anything malicious. Is it Java or Mozilla? It started cropping up when I installed both of those.
