I am probably going to need a new video card, but wanted to ask your advice. I have a five year old early core i7 pc running win10 (upgraded from win7), and have ongoing video problems. The video card is the original nvidia geforce gtx 470 1gb card. I get random shutdowns, and the pc then reboots and I get an error message of display driver failure. On occasion the pc will be able to recover and the display reappears, but most of the time the system reboots. I run the auto driver updates, and this has been happening for a while now over more than one driver from nvidia. I'm starting to wonder if this could be hardware and not software. Since the card is so old already, I'd be willing to upgrade cards if that is the only way to stabilize my system. I'd need some advice on what card might work for my now older system that is stable on win10. Thanks!
