Hey.
After having issues with crashing under load. I bought a new PSU to try to fix the situation. At the time my GPU a inno3D 980ti OC handled stress testing in FurMark etc. But load in a game and my PC crashed. After rebuilding my pc worked fine for awhile but suddenly I had a hard crash and my PC wouldnt start anymore. No fans, lights nothing.

So I took it down. And got it to post with just the MOBO, CPU and RAM installed. But when I install my GPU it just wont get any power. No fans turn on no nothing. I hear my PSU click that all. I tried a different pci slot but it didnt help. Can anyone help?
All help is appreciated
