I have a homemade computer that has been running fine for over six months. I use the computer for just normally daily uses such as music, videos, and games. Recently I had to move. Prior to moving I my computer was handling everything just fine, a few days after the move I finally got my computer back up and running again and attempted to play Skyrim, the game ran at incredibly low framerates even on the lowest of settings. It took me only a short period of time to realize that my computer was running my on board graphics processor instead of my GTX 680. I opened up the NVIDIA control panel but couldn't get my computer to switch over there so I headed to the control panel. There I decided to do something stupid and try to take a shortcut, I disabled my on board graphics with the thought that my GPU would be the new default graphics processor, I was wrong. My display went out and I was unable to turn it back on. My friend who is far better at these things told me to reset my BIOS which I did both with a standard reset, then again by taking out the battery. This hasn't changed anything and I have no display whatsoever. How can I turn on any display so that I can change my settings?
