Hey there. I was recently playing Path of Exile, and whilst roaming among the Video settings, I came across the option to change Graphics Devices or such. When I read what was selected, it said Intel HD Graphics. I thought this was odd, due to the fact of me having put a GTX 660 TI in the system. I looked through some things, and thought about it, and I came to the conclusion that if I disabled the Intel HD Graphics then the system would default the graphics device to the GTX 660 TI, and it would be fine. Unfortunately, it was not so, and now I get no display on my monitor. Did I dun a massive goof, or is there something I can do that won't involve going to a computer shop, or do I need to see a professional?
