I have a 1080 ti and for the last week, every time I turn on my PC, it works for about 10 seconds. It takes me to the main screen but once I press an application, both screens just turn a solid color and i have to restart. But once i just use one monitor, it works. On either monitor, doesn't matter, if its on my HDMI one or display port, if it's just one, it works perfectly. But once I plug both in, it crashes and solid screens. Everything I have seen online that this means that the GPU is dying, but it works perfectly with one monitor, so can it be something else?
