Get your GPU out of PC and see if it boots from integrated graphics. If it does, go to BIOS and set an option to always boot from integrated graphics. Return your 980ti to the PC and see how it goes. If it boots, go to Device Manager and if your 980ti is even recognised under video adapters.

If it's not recognised - it's bad damaged. If it's recognised, you can try flashing the BIOS of your NVidia videocard. You can find guides on that by googling.

That's what I would do first.
