nv4_disp.dll BSOD with new 9600gt

tushkidon · 05-07-2009, 01:57 PM

Hi guys,
I read a few threads with almost exactly the same problem as mine, but none of them have helped so far, so here I go.

I have a brand new XFX 9600GT card and for some reason it's been acting bad.
I'm fine with playing bioshock(with little difficulties), but when it comes to assasin's creed, after 5 mins or so of the game, the monitor just goes black, freezes, and the only thing left to do is a cold reset; sometimes it straight away goes to the BSOD with a nv4_disp.dll problem.

I can do all other work on the pc peacefully. I've tried uninstalling and re-installing the display drivers.

I've got an ASUS M2N-SLI DELUXE mobo, with nforce 570SLI MCP.
Power supply:ZEB-400W PLUS(20+4 pin)

Here's my system specs(dxdiag) attached.

Any help is deeply appreciated.

It's most definitely that power supply your using.

It doesn't have enough wattage or amps on the 12v rail (only 17) for a 9600. When you use a low quality or low wattage power supply it can generate artifacts , overheating , or even blue screens (like what your experiencing).

It really should be a decent quality 500w or higher for a 9600 with 26amps on it's 12v rail and to be 80+ efficient. These are some good units to consider

Hey emosun..

I guessed earlier that the problem might've been 'cuz of the PSU, but i realized yday that one of my memory slots had stopped working, and it was showing only 1gb RAM(which was actually 2 GB), so i used another slot to make it 2gig again, and now everything is working smoothly. Not any blue screen till now(about 5hrs of continuous playing) :)

Anyway, i'l consider ur advice on getting a decent PSU. Thx

So could the insufficient memory be a problem? Or is the prob gone just for now?

With that powersupply I can see it happening again very soon.
