Pretty much almost every night now, but not at exactly the same time, I wake up to a video playing on my computer. In the middle of the night, I'll hear noises, go to the computer room and there will be a video playing inside the Windows Media Player. I turn it off, then nothing.
I chalked it up to the cat stepping on a specific key and never thought anything of it. The only odd thing was that it was always the same video (out of a couple of .avi videos on the desktop). The only other suspect I thought about was my ex-wife, but then, it's kind of ridiculous for her to sneak into my house to turn on a video, then leave. Right?
Last night, I stayed up late reading a book sitting on a couch next to the computer. All of a sudden, out of the blue, at around 1:30 am, the video started playing—just like that.
I checked the process list, ran anti-virus, checked for malware—nothing suspicious. I checked scheduled tasks—nothing there but various Google updaters. I searched the keyboard for electrical shorts that might cause this—but it seemed in a relatively good state.
What could be possibly be causing this problem? Should I call the Ghost Hunters?
EDIT: One other thing I remembered that may be related. Sometimes, the monitor is in sleep mode and all of a sudden it will come on, even though there was no mouse or keyboard activity.
