Hi,

I bought a new case and aio water cooling for my pc. After I moved all the components to the new case and installed the water cooling I tried booting up my pc. It turns on when I press the power button (all fans spin, light in the water pump turns on) however my computer turns off less than a second after I turn it on. Do you know what might be the possible cause(s) of this?

I bought CM mastercase pro, Nepton 250m.

My other components are

Mobo- gigabyte z87x-d3h
Psu- inwin glacier 900w
Evga gtx 770
Blu ray drive
1tb harddrove
Samsung 250gb ssd

Thank you.
