I'm having some very odd issues. Today I was playing the Witcher 3, when all of a sudden the screen went black. I was forced to pull the plug on the pc, as I couldn't do or see anything. On reboot into Windows, I got a message saying that the system had recovered from a BSOD. Using BlueScreen Viewer, it appears that dxgkrnl.sys, dxgmms1.sys, and nvldmmkm.sys were the responsible files. (I've attached a photo of this output)
Thinking it was a random fluke, I started up the Witcher 3 again. Within a few minutes the power to my system went out, everything died. I thought maybe the house had lost power, or at least the circuit, but my TV and DVR were on the same power strip and were unaffected.
When I went to turn the PC back on, it turned on for about half a second then shut off. I unplugged the power from the system, waited, plugged it back in. Tried to turn the pc on again, but it didn't do anything this time. I unplugged the internal power connectors from the graphics card, utilized the hdmi on my motherboard and the system booted up fine. I left it running for 2 hours, and it was okay.
Powered down the PC, plugged the power cables back into the graphics card, tried to turn on the PC and the computer came on for only half a second again.
Removed the Graphics Card, put in my old GTX 580, the system turned on fine and has been running fine for a while now.
Does this indicate a Power supply failure or a graphics card issue? If it was the graphics card, why then would it cut power to the rest of the PC?
If it's the power supply, shouldn't the PC be having troubles with the 580 too? The 580 does use more Watts after all.
