Hi all!
This is my first post. I need help!
Just bought GTX 970. Had GTX 580.
First, uninstalled Nvidia drivers with DDU and turn off. Took out 580. Installed 970. Turn on. Everything great so far, I'm at Windows.
CPU-Z recognize it as generic video card, of course, as drivers aren't installed yet.
I download latest Nvidia drivers (347.25). Insallation starts. Then, a windows sound, and black screen. Mouse and keyboard seem to still work. Monitor doesn't say "no signal". There is signal, just all black. Can't do anything, as I can't see. After a while, PC restarts, but after Windows logo, black again.
The same with HDMI or DVI. On board GPU already disabled. Mother BIOS already updated. CMOS cleared. Tried with 344.75, and 344.80, the same. I even formatted PC. So everything is clean.
I don't think is a hardware problem because it works ok before installing Nvidia drivers. What can I do?
Thank you!
