Windows 7 - Graphic crushing PC

Hello guys,

I am sorry but this post is maybe here more than two times. Well, but my problem is kind different than others.
Like you can see in title, I have problem with my graphic driver. Always my PC get freeze with system message :
Display driver NVIDIA Windows Kernel Mode Driver, Version 285.62 stopped responding and has successfully recovered.

I can install original driver from Windows, HP (HP Pavillion dv7 PC) or NVIDIA driver - I am still getting same problem .. I found some tutorials how to fix it..like some one say use "Driver Sweeper" run it remove all drivers and install new one from NVIDIA web site. It doesnt matter what version of driver ALL showing it

Problem is it wont work..I am getting BIG blue fatal error where say " graphic driver isnt upgraded or something like that.
I have Windows 7 64b Ultimate. My notebook is HP Pavillion dv7 with graphic card Nvidia GeForce 9600M GT.

I think guys... there is just something wrong with my PC or I have no idea.

It's been my experience that that usually means failing hardware

whats wrong with hardware? Well I am trying to fix it as soon as possible because 2 months+ Diablo 3 is comming .. no realy its kind wierd always just push the button turn off PC and again turn ON for that blue fatal error.

I was thinking to install back original NVIDIA GeForce 9200M GS/9600M GT Video/Graphics Driver HP Pavilion dv7-1280ec Entertainment Notebook PC - HP technical support (Slovakia - English)
Maybe it helps..what do you think? but from nvidia web site there is newest for my PC 2011.10.24 version.... and from HP site there is 7.15.11.7904 A ... I am kind confused

Nvida has been having that kernel driver not responsing forever since their latest drivers There is no specific fix.. but apparently going into Nvidia's control panel and setting power management mode to Prefer maximum performance under Manage 3D settings might stop the error (it has stopped for me also)

That's the best suggestion I have heard or found...more than worth a shot....

Well it did used to help... but I already had that damn error twice now

Still was worth a shot...I'll see if I can get some more help

Either nvidia doesn't recognise the issue or they haven't found a permanent solution yet.. and this fix is suggested by users not themself I beleive

Thank you guys for your advices about my issue. I was trying to contact Nvidia support .. some guy called Rashid asked me few questions like :
1. What mode of installation you selected while installing the graphics driver i.e. Express or Custom?
2. Is the issue specific to any game or application or random?

I answered him so I try it here yet.

WolfSoul.. Yes I know about that Graphic control Panel - Manage 3D and PhysX change to Procesor. But I am not sure if this not hurt to play PC games

I wouldn't advice to put PhysX to CPU.. if you found advice like that somewhere they probably meant change it to your videoard instead of autoselect
