Some time ago I was in a train, when I heard a guy saying:
"Don't be afraid, talk to me about your problems, I'm a hardware expert!"
I began to hear even more: I was sure not to be wrong.
The man asked:
"I can't make my vodafone card to work, do you think it's the RAM?"
The guy: "It could be. Is it a desktop or a laptop?"
Man: "Well, it's a laptop"
The guy: "Too bad, if it was a desktop it would be really easy: you just needed to take your RAM, put it into the alcohol, clean it and put it back in the PC. Usually this solves all the problems"
The train travel was long, we are not finishing here.
