I'm using my mum's iMac to write these posts :P
But good news! My computer actually works now! What I did was cleaned it with a paintbrush to get most of the dust out, and disconnected and then reconnected all of the cables, then after playing with the cable at the back and the power switch...presto! It came to life! I also took my RAM out and back in again.
