Here's a pic of the error. It just happens, then I click Either Send, or Dont Send, and it closes explorer.exe (My taskbar and everything goes away)
then it re-appears.

[EDIT]
I forgot to mention that when the error comes up, nothing freezes, or locks up, I can just move it out of the way, and continue on. But sooner or later, another one pops up, then I have 2, or 3, or 4 of them damn things.
I also defragged a bunch of times, and ran /sfc scannow in the run command, and ran scan disk.
