The weirdness of technology

I did a master's degree in instructional technology. I own a variety of digital toys. I love reading about and learning about emerging technologies. But sometimes I just don't understand technology.

Why does my wireless keyboard suddenly adopt strange behaviour (such as when I press the letter Q, and Netscape starts up)? Then after a couple days of head-scratching, the problems seemingly disappear?

I sometimes feel helpless when a relatively simple problem pops up, but I can't fix it. Should I take a course to learn about the insides of computers and computer maintenance? Is it possible to make a computer that actually works?

Arrrrgghhhh!!!!
