With all due respect Chrispy, what you've done tonight is what I did in a computer workshop as a work apprentice nearly ten years ago.
It might feel like a major achievement, but right now most people on here are laughing (hard) at you.
Part of me respects you for having the nuts to brag about something so minor and easy to fix. But another part me respects you for starting to learn about computer hardware.
First trick of the day: Get an old, tired PSU. Plug it in, and unplug after a second or two. Dismantle PSU, remove PCB completely from PSU chassis. Short the pins of any of the big capacitors with a metal screwdrivers - enjoy the spark. This is safe if done properly, and you don't touch the metal part of the screwdriver while shorting the cap.
Second trick of the day: Again, dismantle PSU, remove PCB completely from the metal PSU chassis. Get a large piece of tin foil, and put the PCB solder side down on the tin foil - but don't touch the tin foil while the PCB is on the foil. Plug PSU in, and turn on at the switch. Enjoy as the sparks fly, and the trip switch/fuse in your fusebox trips. Again, this is safe if done properly - and even safer if you do it outside, to avoid fire hazards.
