I just started playing Battlefield 1. Last 2 days 2 separate times my tv want into red, yellow, blue and black "solid colors rotating. Before that when I would turn my computer on it would say " the previous overclock settings have failed and have been reset to default" it has been doing this for a couple weeks. I never have overclocked anything. And now my computer won't give a signal with and graphics card I have, hdmi and vga/dvi. I have unplugged and replugged a dozen times, I have switched memory slots, I have blown out dust. I have done everything I can think of, can anyone help? Thanks. I have taken out the cmos battery and tried to reset and nothing. I can get a screen on anything
