Problem: After removing old Nvidia drivers, monitor went black with no signal after about an hour of playing. I am using a Gigabyte 660 GTX (GV-N660OC-2GD). Nothing was overheated, and I bought a new PSU (EVGA Supernova 750G2) today thinking that it would solve my problem, since everything I've read on the internet states that I had a faulty PSU. But it did not and I have wasted 150$ by replacing a working PSU. I'm actually language mad.

Both fans are running on the GPU.

I have tried:

Internal graphics, works
Old GPU (Geforce 8800 GTX), works
Resetting bios, did not help
Fresh install of OS, did not help
Replacing cables, did not help
Trying different ports, did not help
Blending my GPU in my Raw x1500 PRO, did not work

Why would it stop working all of a sudden? Yes I had the right drivers. The strange thing is that I have a third card that is not recognized either. It only finds my old 8800 GTX. And it also won't let me install drivers since nvidias installation can't find compatible hardware.
