BSOD on Win7 32-bit Nvidia 9400GT

[shdkpr2008]

Hi everyone,
Suddenly Yesterday my computer got crash in an 'nvlddmkm.sys', a blue screen got up with dumping i restarted and tried every trick most
1) Driver Reinstall (Downgrade Version 260 to 257), but no luck
2) I Extracted 'nvlddmkm.sys' from the driver files and copied in many locations : 'DriverStore', 'Driver', 'System32', but no luck
3) I check in 4 systems and none works
When i delete the drivers in safe mode it got open the windows also when i install ' Standard Display Adapter' Drivers it works,

Also on Startup of computer it start showing the lines blue and red dots in a sequence of lines 4-5 tow times and the character are not looking well.

I tried every tick, you guys are my last hope !!!

Here are Dumps Attached .
And A Screenshot of GPU-Z which is horrible ( I installed the driver and not restarted the windows and i captured this.)

Regards
Taha Abbas

This usually means that either the problem lies in your graphic card or in your RAM
Test your RAM http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

Then reinstall the Nvidia Drivers Nvidia driver

Then switch back to the 9600, as its not giving you any problems, and return the 9400 ... Good Luck!

its in warranty i will try to return it .... Is there any way to solve this problem ???

This sounds like a defective card, so no, I don't think there is anything you can do, other than returning it...
