Having just finished installing windows on my new pc, i had just plugged in another hard drive into the sata port and when i started up the pc started to smoke.The pc was working at this time as i could see on the screen.(I had been out of the room for about 20seconds) I quickly unplugged the power plug from the pc but some of the cables had melted already as well as the end of the one "plug" running from the psu.
Not sure what happened, does any one have any ideas.
