idk what's going on here.
i don't really know if it's my graphics card (i don't think so) or the drivers.
i ran occt, furmark, unigine heaven, 3dmark 06 and 3dmark vantage without problems.
i did have problems on unigine heaven but that was related to the program itself (installation) and reinstallation fixed it.
no errors on occt with occt test and vram test with 100 passes.
furmark max temp at 1920x1080 full screen and xtreme burn was 75c with fan set at 75%.
3dmark06 and 3dmarkvantage ran great. i even overclocked card to FTW speed and ran great.
how i got BSOD:
after i ran 3dmarkvantage i send my score to futuremark ORb and then checked my other scores.
after that i opened evga precision and i clicked on the reset button to reset fan speed and FTw clocks that i had.
after i press reset i got a BSOD with the known nvlddmkm.sys describing the BSOD.
so is this a driver related situation??
why i didn't get that while running benchmarks??
i just hit reset and it happened.
i will reinstall driver the safe way and check again.
i didn reinstalled drivers last time the safe way.
should i disable the nvidia high definition soun thing on the manager??
i've seen people with problems and disable it solve it.
any solutions or comments welcomed.
thanks

ok so i just reinstalled drivers using the safe method from evga of curse.
now i still have the nvidia high definition sound devices.
so what i did was disable it using the method on the 400 series sticky until nvidia comes with new drivers so we don't ahve to install the high definition sound from nvidia if we dont use it.
thanks for the comment. i was gonna do that but i remind me of disabling the hdmi sound on that threat.
thank you
 

ok it happened again.
but on the same program.
i ran 3dmarkvantageon stock settings.
then i raised card speed to FTW settings on evga precision.
i ran 3dmarkvantage again without any problems DURING de benchmark. after the benchmark finished (got good score) i closed 3dmarkvantage  without any problems and then i opened evga precision (2.0.0) and i clicked on the reset button to reset everything back to stock settings and the fan to the normal 40% and then i got the BSOD again.
whenever i overclock and after im done i try ti reset using evga precision and it gave me BSOD.
i think is driver related since i don't get any erros or something on occt, furmark, 3dmark vantage and 06.
only when i tried to reset.
why??
should i install the BETA drivers??
thank you.

No need to freak out bro
It just a problem with resetting your OC and Precision... your probably not letting all the Vantage processes close. Either that, or your videocard temps are still to high when you reset defaults. Never drop fan speeds or shut off your computer untill videocard temps are below about 55c. (personally I wait till they are below 45c) 
-->No need to change or re-install Nvidia drivers, just reboot and you will be fine.
 
There is nothing wrong with your card or the Nvidia drivers
  
 

Instead of pressing reset what happens if you lower them back manually. It might just be an issue with resetting the cards not the driver or cards themselves

I would recommend going through the whole process of safe mode, driver sweeper and everything. I have read that the beta is supposed to clear it out but I dont know how well that works yet. adn yea it might just be that something is still trying to use the graphics card so when you hit reset it doesnt like that

Glad to be of help. Just wondering are you running any other monitoring utilities such as hwmonitor or eleet? If so sometimes those mess w precision if theyre open at the same time so that might be the issue as well.

Ah ok. Then yea it was probably that something was still running when you would reset or there was some kind of conflict. How long would you wait after 3dmark was done before hitting reset

I bet you that was the problem. Next time wait 30 seconds or more before resetting. And now im very curious what did u get as your 3dmarkvantage score?

Well thank you. Apparently we both got blue ribbons. And Im not sure what the 460's get on vantage but that does seem like a pretty good score. If it starts acting up again let me know and ill try to find out more

great_shovel i got news!!
good news!!
i uninstalled 258.96 drivers and then updated to 260.63 using driver sweeper in safe mode and also unsing the nvidia cleaning option.
i didn't install the HD NVIDIA sound and 3D driver from nvidia.
these new drivers did the trick!!!
now i don't get errors in unigine heaven benchmark.
3dmark06 and vantage got a increase score of 1-2k
i went from 17k gpu overclocked to 20k gpu overclocked with these!!
now after closing 3dmarkvantage or 3dmark06 i check scores and then imediatelly reset all clocks to stock using the reset button and i don't get any BSOD or errors or freezes. working like a charm!!!
in fact, i tested with these drivers and 3dmark vantage like 4-6 times with and without overclocks on both gpu and cpu.
NO PROBLEMS!!!!
thank you for the help. i'll update with some future info on this.
thank great_sholve.
u earned that BR
