Graphics Card Crash?

[TehBearz]

I recently upgraded my motherboard and CPU. Everything was working fine until my screen went black and my monitor went into a sleep like state then wouldn't wake up. The computer would stay on but the only way to shut it off was to pull the power cord. The fan on my Nvidia GT 520 would shut off while everything staid on. Thinking it was a power problem I upgraded to a 800 watt power supply. It still happened so I then down graded the driver to 296 and it stopped for a while, but now it does it more often than before. I've tried everything I could think of, please help.

Nvidia GT 520 Graphics Card
AMD 8 Core CPU
MSI Motherboard
Corsair GS800w PSU

It could be a defective card. Can you try the card on a different PC? Have you tried some different display cables as well?

The only other pc is my brothers which is the exact setup(sane graphics card) with a smaller psu. But the same thing is happening to him as well. I haven't tried a new cable yet. Could it maybe be seated wrong or something?
