Wow. That's not as bad as my dorm mate across the hall. The other day I had my PC open on the floor (new CPU heatsink) and he walks in and is like, "whoa, cool computer," and he sits down and starts touching things. Then he's like is that the processor and he touches it with his finger (still had thermal paste on it, lol.) So I calmly (barely - I hate the kid) explained that you should never touch it, it has to be sterile for heat transfer, etc...
When he hears that, he says, "So like, it has to just have that goopy stuff and nothing else?"
"Yea."
"Oh, well thats good, cause when I got my processor, I tried putting that sticker on it, cause that's what it said to do, but I took it off cause it wouldn't stick..."
"Wait, like the Athlon 64 sticker?"
"Yea - that's not where it's supposed to go?"
...OMG - he was freaking SERIOUS.
Then he goes on to tell me how now he has a water-cooled rig. I can't imagine someone that stupid possibly having a computer setup like that, but he really seemed serious, so IDK.
