[Chalky] I think he means he's deeply worried someone might try winning the game while he's working on it - big bangs, flashing lights, tape spewing on floor, "MALFUNCTION - DOES NOT COMPUTE," sparks, demolition of The Institute, "the reactor's gonna blow," alarms, emergency lighting, "dive! dive! dive!" and so on.
[Inks] Yes indeed, which should tell you that it wasn't me trying to end the game .. or SO YOU THINK ... [Darren] Gosh. Joking apart - is it possible for a computer/server to malfunction to such an extent that it really would explode or even spark and sizzle a bit?
[Chalky] If the power supply goes, then yes. If they're overloaded, they will often overheat, and sometimes (like mine did last year) go "pop" and stop working - that's if you're lucky. Some will actually explode when they're overloaded. Some will simply make a loud bang and smoulder. Others may suddenly start pumping out more voltage than your machine can take, which could cause other things to go bang. So if you do a bit of home modification, do take care that you don't overload your PSU.
