ok so I have a strong enough power supply 1000 watts enermax and a few months ago my screen started to go black for couple seconds and precision would still be running but i could hear the card fan speed drop to almost nothing.
 
I updated my drivers then and all has been fine since.
Today I got up and my monitor went black several times with card fan speed droping alot.
I just seen theupdate for bios and fanspeed so i updated the card with that got the newest whql drivers andran oc scanner no artifacts detected, however at the time when my monitor would go in and out i would see little green spots not many but a few randomly on the screen.
 
but since i updated bios precision, and drivers have not noticed the fan dropping or black screens. is it possible my card is slowly dieing? or could it have just been a driver issue? neevr had this happen before but i have ran stress test and gpu benchmark with oc scanner and no artifacts detected or seen.
 
thanks for any advice or experience with the black screen and fan dropping to 40% or so.
