GPU driver reset when Graphic Card is in PCIE-16X slot

Iordache Cosmin · May 20, 2015

Hello, I have a strange problem and hopefully someone can help me. My specs are these:

i5 3570k
2x 4Gb G-skill DDR3
MSI Geforce 770GTX
650W PSU (Inter Tech Energon EPS-650W - http://www.inter-tech.de/index.php?option=com_content&view=article&id=615%3Aenergon-eps-650w&catid=125%3Aausland-atx-Power%20supplye&Itemid=542&lang=en )
Asus P8Z77-V LX Mobo

So, I find my problem rather strange. The nvidia Display drivers keep restarting sometimes only when I start a new stuff (ranging from start chrome, my computer or battelfield 4). This happens just when the GPU is seated in the main PCIE-16x slot. If the GPU is seated in the secondary PCIE-4x slot I never ever get a crash...

Another intereseting thing : If I start MSI Afterburner and for my GPU in it's first state (like under load) I won't get crashes.

So this makes my think it has a problem while switching from idle to another state. But why does this not happend when the GPU is seated in the PCIE-4X slot ?? So that makes me think maybe it's a PSU problem ? But the GPU should not use more power while in 16X slot, right ? Or maybe a faulty MOBO ?

I have already tried :

5 different nvidia drivers, all same result
updated BIOS
reseated RAM, GPU
check RAM for faulty segments
same problem in WIN7 and WIN8.1 on fresh maschines

Unfortunately I cannot try the GPU in another computer and do not have any spare GPU, MOBO or anything else.

So my 2 questions to sum it up:

What seems more likely to cause this behaviour ?
Any idea on how to fix this without replacing hardware ?

"The nvidia Display drivers keep restarting sometimes only when I start a new stuff "

Are you getting some error message saying this? How do you know?

That power supply is most likely the issue.
300w garbage in disguise.

Never cheap out on the heart of your pc.

Test your system with a proper power supply.

i7Baby :

maxalge :

Screen flickers temporarely, the chat bubble on windows with the nvidia display driver has stopped working but it has been resetted, the application gives rendering errors and a dump is made on windows with the nvidia driver as a culprid.

Perhaps I will get a new PSU, I find that PSU wierd too.

I have bouth a good PSU and now the problem is gone. I am not 100% sure I understand why the GPU needed less power in the PCIE-4X slot, but I have also seen that the given PSU did not natively had a 6pin PCIE and a connector was used from 2x molex.

Perhaps because a connector was used and given the fact that the PSU was crap it did not need enough power to supply the higher bandwidth given by the PCIE-16X speed...

Anyway, if someone could explain the problem would be much appreciated, I find this interesting.
