Well, my first resort if anything "strange" is happening, is first to check the system for malware. Some is designed just to annoy you.
Download this; Malwarebytes
and run a FULL scan. If it finds anything, post the log here.
Although I have Norton Internet Security 2011 & Spybot insatled,
I got Malwarebytes, but nothing was detected still.
