Turns on, lights up, fans spin for a second, turns off! Help!


Sep 12, 2011
I know this a very common and vague question, but here's the thing. All my components are compatible, I just upgraded my CASE. I'm using:

Corsair TX750 PSU

Gigabyte z68-ud3

16 GB Corsair Vengeance (4 x 4GB)

The problem is not the GPU, because I've unplugged everything but the CPU and the power button, one stick of memory, and CPU cooler. Still the same.

I also removed the motherboard from the case and tried again, in case it was somehow shorting there.

Please help! This was working a couple of hours ago, in my other case. I have no idea what could be different, or wrong. :( :( :(
