Kicking, It sounds like your power supply is dying. It happenned to me once, I turned on the computer, heard a small 'pop!' from the back of the machine, and nothing turned on, it did look like something very bad (!) happened. 25$-45 $CDN and 4 - 6 screws to change the power supply . Make sure you got the appropriate power supply, 250W to 350W depending. Cheers!!
I hope you got the dish set with little imperfections to prove they were made by the indigenous peoples of...wherever... to match your rugs.
I have my box on a rug, Brought it into CompUSA for hardware purchase and free install, paid for a powerclean..it is amazing how much fluff your fans will suck up, another month os so and I think I would have been in trouble. Now have the Box sitting on a wooden plank, on the rug. CompUSA can give you a good powerclean cheap, and even install some extra fans if you need them.
