Possible solution is posted on nvidia forum:

http://forums.nvidia.com/index.php?showtopic=102344

Anyone tried this?

I read this and found a way easier to do that,I made a REG file and I'll upload it here,you can download it and try,but it DOES NOT work on my notebook(V80H86vn-SL,9650M GT 1G RAM,Vista 64 SP2,186.03WHQL),if it works on yours,please tell me,thanks.

the content in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm]

"EnableNonContiguousSVM"=dword:00000001

fix.rar

Finally I gave up and installed the driver 185.70,every thing works perfectly,even the sound card works better than before(in World of Warcraft).

32bit

64bit

So,it means that ASUS konws how to do and the problem may be fixed by the new version drivers,just wait.

You made my day!!!!

I'm also an owner of a M50VN and had nothing but troubles for the past 5 months.

I would get random freezes (everything including mouse pointer hanging forcing me to do a hard reboot) maybe once every two days of normal use.

This happened with all nvidia drivers, from stock until before the 186.31. So it was difficult for me to pinpoint whether it was a motherboard hardware fault or a graphics card issue. This has also happened with all operating systems I tried, from xp to ubuntu.

But I always used the internal lcd. Are you sure the freezes would disappear by simply using an external monitor instead ? :) How did you find out ?

Also it seems with this new set of drivers 186.31 I now get instability (yes the frequent sys file crash notification) but at least I don't have system freezes anymore, just the black screen flickering for a moment and the sys file crash notification.

I'm loosing my sanity with this as it seems a software rather than hardware issue and wished to talk it with you in details, would you mind emailing me to luca.za@gmail.com ?

Thanks a lot

Luca

I'm currently running vista sp2 64bit ultimate up to date and my specs are:

ASUS M50VN-AK008G

4Gb kingston memory

Geforce 9650m gt 1Gb

1680x1050 widescreen 15"

Exactly the same problem with Asus m50vn.

GeForce 9650M GT (bios 62.94.3C.00.35).

Installation of any last Nvidia drivers (from 185.81 and newer) cause system freezes (stable bug, problem reoccurs every bootup). Tested on Windows Vista x64 sp2 and Windows 7 x64 (build 7137).

Looks like that problem happens only then built-in notebook lcd is active, but if dispay device is switched to external hdmi (e.g.) - no freezes, everything is ok.

same problem with my asus pc, running windows 7 rtm and geforce 9650m gt

no driver wokrs on it....

somebody should tell nvidia about the problem....

Hmmm that was a while ago ... but yeah i have the problem too with my Asus Pro72Vn with a 9650M GT 1024MB. Reported the errors to Nvidia and Asus ... Asus: "we don't support Windows 7 Issues" ... when i told them it happens on Vista too i was advised to RMA it. Nvidia never answered to Feedback, forum and e-mail ... customers can be such a pain in the arse :-P

If it helps I am still running my Laptop now with Windows 7 RTM (Sorry for that, Asus) and the DOX modified Forceware 182.46 with no issues. I'll keep it that way till I buy a new one... ya no Asus anymore and some ATI graficscontroller in it ;-)

Hey guys,

just found a possible solution in the nvidia forums. Haven't had time yet to test it, maybe some of you can try :

Possible Solution

The problem seems to be the Nvidia Powermizer. When the registry settings are changed it seems to work again :-) Please write here, if it worked for you :)

Cudos for the guys in the nvision forums :)

Greetz, Averius

I have the ASUS m70vn 64-bit with the GEforce 9650m GT 1 GB. Tried updated driver with vista and had to roll back to original ASUS supplied. Upgraded to windows 7 64-bit and the problem still exists. Can only use the version available from ASUS site. They also have no windows 7 drivers for the other things that break yet like the webcam, the fingerprint reader, etc. They just say they will become available in the future.???

look on their ASUS Support or google for unofficial asus boards. there is a german page for drivers AsusTreiber.de . found the m50vas.212 bios update there ;D

try to install vista drivers.. some drivers are not available.

hi,

found yesterday this topic and was happy that i'm not the only one having this issue!

i wrote to nvidia a email and still waiting for a response.

but in another thread i found this registry tweak

"\ HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Video \ (* a series of numbers that are different *) \ 0000 \ PerfLevelSrc"

Change the value of "PerfLevelSrc" from "3333" to "2222"!

change "powermizerenable" to "0"

change "powermizerlevel" to "1"

and "powermizerlevelAC" to "1"

in the modded inf it looks like this

[Mobile_Tweaks]

...

;Powermizer settings

HKR,, PowerMizerDefault, %REG_DWORD%, 3

HKR,, PowerMizerEnable, %REG_DWORD%, 0

HKR,, PowerMizerLevel, %REG_DWORD%, 1

HKR,, PowerMizerLevelAC, %REG_DWORD%, 1

HKR,, PowerSaverHsyncOn, %REG_DWORD%, 1

HKR,, EnableCoreSlowdown, %REG_DWORD%, 1

HKR,, EnableMClkSlowdown, %REG_DWORD%, 1

HKR,, EnableNVClkSlowdown, %REG_DWORD%, 1

...

;PowerSupply settings

HKR,, AllowMaxPerf, %REG_DWORD%, 2

HKR,, PerfLevelSrc, %REG_DWORD%, 0x2222

HKR,, RMEnablePowerSupplyCapacity, %REG_DWORD%, 1

HKR,, RMPowerSupplyCapacity, %REG_DWORD%, 3

and applyed this to the .inf from here for the newest driver and i can say it is working until now :)

without this changes i got every time system freezes!

Using Asus L50Vn having a 9650M GT

Regards,

Sereby

I have a total solution for this problem, I fixed it by updating the BIOS from ASUS support site, use M50VN and not x57vn if you have other model check under your battery and use that to search for your model, then:

Download the latest bios (in the description it says that it fixes flicker problem etc, THANK God!)

then download the Bios Winflash and run it but when you do this, make sure your laptop is charging at the same time and close every applications. and then run Winflash to flash your BIOS.

and you should be able to use your computer without any problems, then after that update your gfx drivers from laptopvideo2go.
