Last night I was playing some Dota and suddenly the fuse blew. I could swear I saw a spark coming from the top fan of my computer but I might be wrong on that as the fuse blowing really suprised me. I went to the fuse cabinet and usually I've only needed to flip the switch back up, but this time the switch was at the middle position and couldn't be flipped down, and flipping it up wouldn't help, it would just flip down again. I tried connecting my pc to another outlet and the same thing happened, as soon as the connector hit the outlet a spark showed and another fuse blew.

I'm very ignorant on this kind of technical stuff so I don't know if the problem is the fuse or the computer, but seeing as how I blew two fuses I imagine the problem lies with the computer. I've been told to try the kitchen or the basement since they have stronger fuses, but I won't risk losing the fridge and stove or any other much needed item in the basement. Do you think it's the power supply?

I've had a similair problem before a couple of years ago (6 year old computer) and then I could just flip the switch. However the psu needed to get switched out for a new one.

I guess I could add that there didn't seem to be any smoke or weird burnt smell coming from the computer, the first time something similar happened there was a distinct smell of something burnt coming out of the computer. Also it's peculiar that this has happened to two different power supplies, my original psu was a Corsair 550W Bulk black, and the second, my current, is a Corsair TX 650W. Might it be the other components in the pc? Or bad fuses?

Hi,
Just throwing this out there, but I had a similar problem when I recently moved into a new place. My computer which had previously run fine at my old house, would constantly keep blowing the breaker when using it in my new house. I did not have any issues with sparks. Just as a suggestion, I plugged my old line conditioner into the outlet, then ran my computer to it. Have not had a single issue since. I am running a mid tier corsair PSU. It was suggested to me by a few friends with electrical knowledge that the breakers that ran that room, were a different type then the rest of the house. I cannot remember the specific name, either a phase type or arc fault type. They were a more sensitive type versus the normal trip type breakers, which were much more sensitive to noise.

With your description of sparks though, and tripping immediately when plugged in, I'd lean towards the PSU as others have suggested. Just thought I would share the additional info, for future knowledge.
