I recently purchased an ASUS N76VZ a few days back.  It is laptop that uses the nvidia optimus technology. The laptop has 2 graphical adapters one a Nvdia Geforce GT 650M and the other intel HD graphics 4000. The laptop is using a windows 7 home premium 64 bit and has 8 gb RAM and i7 3610QM processor.

The problem started when my son tried to run League of Legends ,Dungeons and Dragons and Dead Island. The games would crash and this was the event viewer.

Faulting application name: League of Legends.exe, version: 1.0.0.146, time stamp: 0x503e5fd9
Faulting module name: nvd3dum.dll, version: 9.18.13.448, time stamp: 0x4fd62809
Exception code: 0xc0000005
Fault offset: 0x006b7055
Faulting process id: 0x1b00
Faulting application start time: 0x01cd8b5185fc5df0
Faulting application path: C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\0.0.0.182\deploy\League of Legends.exe
Faulting module path: C:\Windows\system32\nvd3dum.dll
Report Id: e1210298-f744-11e1-b251-685d4386d47b

So I tried using the Nvidia control panel and setting the graphics to use the Geforce card but the problem kept happening. So when I used the default graphic processer overrride option which you can do when launching the game itself  it just went black and had to be shut down via the task manager however the earlier nvd3dum.dll problem did not occur.

I tried the 304.79 driver and the latest 306.02 driver and both had the same problems. I am wondering if my card is defective. Games however work on the hd intel card but obviously I want to use the Geforce GT 650M card. I have sent it to the shop and they have sent it back to ASUS. Any chance this is a software problem and they are going to  send it back with a sorry it sucks to be you message.

Its says it right in the description.  The problem is nvd3dum.dll .  Most likely a faulty driver.  My suggestion is to do a clean driver install.  Its detailed here. http://www.venarc.com/blog/proper-way-install-nvidia-drivers

Also you might need special drivers if this is an optimus laptop because it needs to support both intel and nVidia video drivers, and it needs to swap properly when you play a game.  I would download the drivers straight from ASUS and not from nVidia due to the special circumstances of the video setup. http://usa.asus.com/Notebooks/Multimedia_Entertainment/N76VZ/#download

Yes the intel driver I got from there but I did not get the Nvidia driver from there too thinking Nvidia site would have better. Okay I will try that.

I agree also that the initial problem was the nvd3dum.dll was a driver problem but when I overode the set graphics driver that was not the cause of the game failing. There was no error report on that as the game froze and had to be shut down from the task manager. Also that faulty module path does not exist as that file does not exist in the path they mentioned in the event viewer which was another starnge thing. However on checking my own computer I saw that there is no nvd3dum.dll file but there is a nvd3dumx.dll which both the laptop and my desktop has.

Anyway thank you again you have given me an idea to help solve this issue.

It was according to ASUS a defective laptop but they cannot replace the exact one because they do not have 750gb hard drive version .So I am stuck with having to pay the extra to get the replacement with a 1.5TB hard drive version which will be arriving end of this month. As my nasty luck would have it they have revised their prices too. 

I know these sort of things can happen with a  computer as it has so many parts that can be defective but damn I am mad especially when I was patting myself on the back for getting the earleir one at that price. Should have known my luck was too good to hold. I am now praying the replacement works well.
