Hi I've been having this problem for a while now so listen up
(Screens are below for more info)

When playing just any game it crashes and I get an error messege saying "Directx has encounterd an unrecoveralbe error"
and
Display driver "nvlddmkm" has stopped working.

Then the computer flickers in and out and I am forced to restart the computer manualy.

Thins I've tried is that I formated my main "C" harddrive and setup all newest drivers etc.
That didn't fix this.



Another thing I thought of is that the card was overheating, well it has a custom Thermal Right cooler and a 120mm fan but I still tried and opened up the case.
That didn't have any effect.

This is a strange problem because I am able to run tests such as 3d mark -Vantage, 06, 05 and 03 without any crashes.
It's only when I play games for a while, and there doesn't seem to be a pattern in how long I can play it is totally random.

So any ideas ?

Regards
Hallur

Bump

Shouldn't I have Directx 10.1

After doing what sygnus21 suggested and if you are still experiencing the problems, I would try re installing your drivers since 181 is already out.

Did you recently updated your drivers, say from 178 to 180? if so, did you also uninstall the PhysX drivers and run a registry sweeper before installing the newer drivers?

Games i've played so far have all crashed. Both dx 10 and 9.
It actually first started with Fallout 3 and it's like the lower I have the settings, that's res and deatail, AA etc. the longer I can play.

Games I've played so far since this started have all had this directx error.
Fallout 3
Left 4 Dead
Call of Duty: World at War
ElderScrolls IV: Oblivion

I'll try what you've recommanded and let you know if it works.

Not 100% sure here but I think that Vista x64 requires at least 4GB of Ram to be able to work well, less than that and you are looking for trouble, of course this is only hearsay on my part and, hopefully, someone else will either confirm or deny this.

You have a very good card, even by today's stds and you also stated that you have a cooler but, have you checked your temps?

There doesn't seem to be too much heat... after all I have the best available aircooler for this card from ThermalRight. (See below on pic)

Also when trying to remove the display driver I get this problem.
