I got a new motherboard because my last one started smoking and stuff, and now my computer will not start.
When I try to turn it on, it doesn't even seem like it's trying to start. No fans turn on, not even for a second. No beeps, lights, nothing. I have tried swapping in a new power supply, but still nothing. I have checked all my connections, but they all are right.
The next logical thing that might be bad is the processor. But even with a dead processor, wouldn't it try to start up? The computer is acting like it is getting no power to it at all.

I'm pretty much out of ideas here. If someone thinks they know something that would help, please post!

What's the make/model of the new motherboard (and the CPU)? Some newer motherboards need a 4-pin power connector in addition to the larger 20 or 24 pin connector.

Mobo: Gigibyte DS3
CPU: Intel Core 2 Duo E6300

The motherboard is the same model as before, I was still under warranty so I just got it replaced.
There is a 4 pin connector right above the CPU, labeled ATX_12V also. I have it connected.

It sounds to me like the motherboard is bad. Even with a bad CPU, it should still power up and such. So, unless in turns out that it's not plugged in (this has happened to me, :thumbsup: so double check!) I'd say you need to contact the manufacturerer for (another) replacement.

Take the motherboard out of the case and try starting it, with only the essentials plugged in, on a non-conductive surface.

Wow, I feel like a retard! That worked!! Thank you so much!
Was something shorting out on the case or something? Did I just install it bad?

The mobo wasn't shorting out on the case. One of the front usbs was shorting. Just clipped the wires for it, and works great. Thanks alot everyone.
