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. 

System specs: (should all be in the dxdiag, but just in case a few are missing)

750 Watt Cooler Master Power Supply (4 years old)
Intel i7 2600K running stock speed at 3.4 GHZ
MSI GTX 970 (card that wasn't working right)  *Currently using EVGA GTX 580
Asus PZ68 motherboard
8 GBS of G.Skill Ripjaw RAM
1 CD / DVD drive
3 internal HDDs  (with 3 external HDD normally added too)

Gday pz3shwks.

the GTX 970 uses 2 6 pin plugs, the GTX 580 uses a 6 pin and 1 6+2, so as you noted, draws more power so does not sound like a PSU issue.

 

 

I unplugged the internal power connectors from the graphics card, 

If the card was still in the slot?? it would still be getting power, the system did not crash.  When you reconnected the power cables, (and used a video port??) the system crashed.

Possible a fault on one or both circuits from the PCI-E sockets or on the video port you used.   Test again without a monitor and then again using a different video output.

 

Try the card in the second PCI-E slot.

Hmm, I'm a bit confused.  Both cards have the exact same power pin area.  I use the same 2 sets of power cables for each.  I think there is the 8 pin connector with a 6 pair right next to it.

The card was still in the slot, sans power cables, running off the Intel Integrated Graphics, without issue.

I tried putting the 970 in my second PCI-E slot, system got power for half a second then shut offt.  When I tried it in the second slot I had no video cables plugged into the card.  Just for the heck of it, I also tried it in my 1st PCI-E slot again with no video cables attached.  It just did the usual turn on for half a second then shut off.  (After doing a bit of research, it sounds like that might be the power supply protecting the system and shutting it down due to a short or fault?)

Removed the Graphics Card, put in my old GTX 580, the system turned on fine and has been running fine for a while now.

Appears no short anywhere and PSU delivers the 580s requires 243W TDP. total system draw would be aprox 400W.

Just for the heck of it, I also tried it in my 1st PCI-E slot again with no video cables attached.  It just did the usual turn on for half a second then shut off.  (After doing a bit of research, it sounds like that might be the power supply protecting the system and shutting it down due to a short or fault?)

970s TDP 145W, total system draw would be aprox 300W,  I would say the short is in the GPU and the system is shutting down the PSU, you should RMA the card..

Is it possible to test the card in a different computer?

I don't have any other computers that would be able to fit that card inside.  I've requested an RMA from MSI, hopefully they don't give me any hassle.

MSI are reported to have good support, so you should be OK.

Please follow up and let us know the results.
