Got an Interactive Service Detection popup that said a program was trying to display a message; when I clicked View this message, my monitor changed display settings to show it, but nothing showed -- just a purple-ish screen. The message is due to an incompatible program or something is what some research shows. Eh. Must have hit a button or something. I may also have some Windows XP stuff on it, which I guess would be incompatible, from when I upgraded to Windows 7 on November 25, 2011.
