I have a gtx 770 gpu and whenever I download a driver for it, it asks me to restart my pc(which is normal). I click restart and it shuts off, turns back on then the normal windows loading screen pops up then after, the screen just turns black... I tried waiting for l about 2 hours but still no. To fix this I have to turn off computer then turn it back on, boot into safe mode and go to desktop, then I just delete the drivers, restart my pc go into normal mode and it loads into dektop. But then when I try to download an earlier version of the driver the same exact thing happens. How do I fix this black screen?!
