Ok, so I recently bought a custom built pc from cyberpowerpc and It seems like my graphics card is dead. The graphics card I have is a AMD r9 270x. I have these 2 big lines that go vertically on the screen, and just recently my monitor wont even show the windows sign in screen. The computer starts normally then, after showing the motherboard screen, windows attempts to load, then the screen goes black, even though its still on.
HELP PLEASE!!
