Hi,

My old graphics card (gtx 460) was crashing. Games stopped responding. and sometimes I got an error saying: " Display driver NVIDIA windows Kernel Mode Driver, Versions 258.91 stopped responding and has successfully recovered.)
I tried to fix it by reinstalling drivers, changing settings, etc. But finally decided to get a new graphics card (Sapphire r9 380).
I received it today, but when I plug it in the computer does not start. All fans are on (GPU, case, and PSU (though only at the start), but the monitor stays black, even if I plug it in the motherboard. My back-lit keyboard does not lit up (I don't know if it relevant).

If I remove the GPU the computer starts fine.

Is the problem actually the PSU and not the graphics card? The motherboard? RAM?
Or did I get unlucky and my new GPU is also faulty.

To be honnest I am clueless here. Any help would be welcome.

The computer was built 3.5 years ago.

Specs:
Processor: Intel Core i5 3570K,1155
GPU: 1GB EVGA GTX 460 FPB, 4008MHz GDDR5 (old GPU)
Sapphire Nitro R9 380 4GB (new one)

PSU: 650W Corsair Enthusiast Series 650T
Motherboard: Gigabyte GA-Z77-D3H
RAM: 8GB (2x4GB) Corsair DDR3 Vengeance
