2003 Honda Stream Hazard lights keep blinking

I returned from vacation to find the battery dead on my car. I jumped started it, and after that, the car started acting strangely. Firstly, the car no longer "beeps" when I lock or unlock it from the remote. In addition, the hazard lights blink every so often - usually when I'm driving, sometimes every ten seconds or so, they'll blink three times then stop (people have offered me help, assuming I was in some sort of trouble!). Also, the windows don't roll up anymore when I lock with the remote, as they used to.

My wife said she had this problem in the past, and she thinks that the computer had to be reset. Is there any way I can do this myself (I'm a "do-it-yourself kind of guy, so I have no qualms getting my hands dirty if need be).
