Hi I'm new and new help or guidance. I am running Win 7 Professional on a Vostro 470 i7 with 32GB RAM, EVGA NEX750B power supply. I had a GTX 560Ti in the machine and all was good. I read that a GTX 1080 would give me more horsepower and the spec sheet says it could run on Win 7. Anyway, I made sure windows was as updated as it can be at this time and all was good except for an optional NVDIA - Display - 3/23/2018 -23.21.13.9135, it always fails, 411Mb. Failure is Code 80070103.
I tried the driver installer V 472.12 and it comes back with "This driver is not compatible with this version of windows" and "Graphics driver could not find compatible graphics hardware."
I turned off my machine removed the 560Ti and put in the 1080. I got the Dell logo then it began to beep, about once every 30 seconds. It just stalled and beeped. after about a minute the screen went blank and the windows logo song played as if Win started but no video.
I am open to suggestions. When I put back the 560 it works fine.
Any help would be appreciated.
