Yesterday morning I had a hell of a time getting my garage door shut. Once opened, the automatic garage door wouldn't close. The light on the motor kept blinking as if there was something blocking the door. I checked the beam and lubed the chain, rails, wheels and hinges. Still, the door would not roll down. I released the chain and pulled the door down manually and it went down without a hitch.
Last night, I went home and my wife had managed to get the garage door down automatically. I opened the door, then reclosed it myself and, sure enough, the door went down just like it should have. Weird. Works perfectly now while in the morning I couldn't get it down to save my own life.
I told my story to a co-worker and he showed me this article on Fudzilla about a guy who has two GTX 295 graphics cards and how his garage door opener remote doesn't work when his computer's on. Now, I wasn't trying to use the remote to close my garage door, but I find the irony humorous that this article came out the very next day after fighting with my own garage door.
