EVGA GeForce GTX 770 4GB Dual Classified is the card in question
so this is how it went
Was on one of my long sessions of Diablo 3 about 4 hours in and computer restarted for no reason.
Upon restart video is rather choppy and sluggish. I check desktop right click no nvidia listed so i check device menu and video card is listed NVIDIA GeForce GTX 770
but with the yellow exclamation mark on it. So i do a full shut down pull power reset bios start the machine up again. well low and be hold video was back.
3 days later video card gone again, only this time i did the whole remove drivers restart in safe mode use DDU as well as disable windows updates driver installation.
reboot install newest drivers and seems to be back.
Until i restart my computer and ever since now when i restart i have to install driver do the driver requested restart and its installed till another restart.
I have tested the card in both computers in the house the other machine it will stay after restart some times sometimes i have to restart 10 times and reinstall a couple times for it to see it
Have even clean installed windows which i hate doing.
i have double check mother boards even swapped out with 3 sets of ram but the video card always wants me to reinstall driver after every reboot
being that the card worked with zero issues for 2 and a half years i think its probably safe to say i should probably just RMA this card ? Unless anyone else has some insight as to the problem.
