Oh hell what have I done?
New PC that I built a couple months ago, i7 920, Asus P6T Deluxe, fx nivida graphics card. Been perfect.
Just switched it off to add an extra fan and second hard drive that came today.... simply plugged them in, all nice and simple. Press power button and there is a small spark of light near motherboard followed by electrical crack sound.
Now nothing is powering up. What the hell have I done? It was only a hard drive and a fan. Nothing is overclocked or messed with in any other way. Motherboard is still getting power it seems, reset and power led glowing away.
Please help, heart is racing a mile a minute right now...
