PC won't boot past BIOS after inserting new GPU

[Robin Bastian]

Rig:
PSU: Seasonic G650
Mobo: ECS X77H2A3
CPU: i3-3220

I bought a new Zotac ZT-90101-10P (GTX970) and after replacing my old GPU with it, my PC won't boot past BIOS prompt.
Pressing DEL, F7, F8 or anything can't get me into the BIOS setting.
It even fried one of my PSU

Tried to remove the GPU and my PC boot normally.
Replace my old GPU back (HD5770) and my PC boot normally.
Resetting CMOS didn't work.
this site here gives 5 star rating for compatibility with Mobo.

I'm so frustrated right now. 🙁
Any help would be appreciated.

I'll do it in a few days. Been busy working 9 to 5 I can't even send it back for RMA.
I'm curious, what else can I do in this situation.
