If you are running a board with a new AMD64 cpu that will require the extra four plug be plugged in on the board near the cpu itself from the power supply. Without that new 12v feed there the new AMD boards will not post. Go over all of your power connections carefully. Hopefully that's all it will turn out to be instead of seeing defective hardware(s).

NEVER mess with that switch unless you leave your continent. I did that too, a very good lesson to learn, except we both learnt the hard way. Im pretty sure its just the PSU thats blown. Infact, iirc, it was just my power lead that needed replacing.zap45 said:
You never adjust that type of setting when ac is connected to begin with. Hopefully all you diid cook was the supply. You probably cooked the leads and possibly the transformer. I was going to mention a possible bad board not cpu due to what happened to a friend lately when ordering, returning, getting replacement, and then selecting another model board due to a bad batch the vendor got in. The boards sent also refused to boot while there was a normal light show for a brief second or two. The four wire plug was found to be in as well as double checking connections and verifying cards and memory seated properly. Generally if you switch from a lower to higher input setting fast like that you more then likely only did in the supply itself. Do you have a spare supply onhand to sub for it?You were fortunate that the fuse caught the little surge there alright. A good supply will often have an internal fuse as well as having the breaker switch on the back in the even that gets fused somehow. If no other things are found wrong with the supply hang onto it. What make and model is that one you were running? I see you are not chancing using the current cpu to try out on the board by ordering a second one with the replacement mobo. Or you simply went with a bundle? Hopefully you didn't order the same model board from the same vendor. Someone locally went through three new boards when the first two were useless. Bad chipsets or something there.
Whenever I see a combo board I start to wonder on just how well they are made. Did you order another one of the same or go with a Socket 939 single cpu model board? The power level of the supply should be adequate if the supply there is a good make(Enermax, Coolermax, Antec, etc.)
