Installed it today. The yellow wire was only, like 2cm long. Had to remove heatsink to get it in, replaced but didn't reapply the paste as the paste on there was sticky and gooey anyway so should have re-adhered easily enough. I have yet to buy a parallel port cable but that's not the problem. I booted up the GC to see if I got anything at all - I believe I should have a prompt on the screen? The Cube turns on but nothing comes on screen, and the power light flashes for half a second before going off. Does anyone know what this could be? I'm a bit desperate here!
