I walk out of my computer room. Hmm Why is that computer so quiet? *looks behind it*. The fan failed on the power supply, and the system was running really hot. I shut it down, started to take it apart, stopped for dinner (Roast Chicken), opened up the power supply. Hurmph. 'Hazardous' and 'No user serviceable components inside'. Whatever. I'm a user, and I can fix these things. Loads of dust in there. Vacumn them up, and the vacumn cleaner starts to choke *ghhhg*. Re-greased the fan, put it back together properly, put it in to test it. And then it shocks me. AFTER I have dealt with the high-voltage components. Bah!
