"Display Driver nvlddmkm Stopped Responding and Has Recovered"

[sdwalid20]

hi,i've VGN-NR21S i bought it nearly one year ago, it worked perfectly until few days ago when the screen go black,sometimes it comes back to normal with a message "Display Driver nvlddmkm Stopped Responding and Has Recovered" or i have a blue screen and my pc reboot.

i tried to delet/install the nvidia driver but still the same, to get it work i've deleted my nvidia driver, i know it not advised

by the way i have a nvidia geforce 8400M so i'm asking is it a compatibility problem with vista or is there something odd with my graphic card ??

If you have overclocked then undo it.

if you have maxed your ram take a stick out.

don't forget

Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel.
Start
Windows Control Panel
Add/Remove Programs
search for “NVIDIA Windows Display Drivers” or “NVIDIA Display Drivers” and select remove.

DO NOT over install!

try THIS driver

i didn't overlock it nor have i boosted my ram
and before the problem apears i had even never changed my driver
and i always erase nvidia display driver
i will try your driver

it says that my hardware isn't compatible

do you know what card you have, i guessed as i know overclocked forceware ones were pulling that error.

nvidia geforce 8400M and over one year using it i never had a problem

[simbaron2]

are you running XP or vista? did they update just before the problem?

have you tried something as simple as a system restore?
