I'm not sure what happened. I was getting a message on my desktop talking about ATI Catalyst not recognizing my display adapter. After doing some quick research I read somewhere that I might need to disable my onboard video. I did that, and the screen went dead.
I came back a few minutes later, and it was magically back on. Unphased by my previous disaster, I did something else that someone recommended, namely uninstalling the Catalyst Control Center. When I turned my computer back on, there was, again, no display.
Please help me. If I can get this fixed, I promise to stop listing to my instincts (without asking first).
The thread that said to uninstall the Catalyst Control Center was for someone who was upgrading FROM a Radeon card to an Nvidia card. I built a new system with an Asus 7870, and am just trying to get the system to fully recognize my new card. These are clearly different situations.
