Hello! My problem started when I was playing a game. The screen just went black and the monitor just went to sleep. When I turned it back on, it just cycled through the inputs, said "No signal detected" and went to sleep. I just held down the power button to turn the computer off. When I turned it back on, there were light horizontal lines on the screen. Windows booted up, went to the loading bar and then the monitor went to sleep. If I turn it back on, it'll just cycle through and just say "No signal detected".
I've tried reseating everything except for the mobo, cpu, and psu. After reseating everything, I got the "Boot mgr is missing" error, so I just did a clean install of windows. I've changed the slot the card is in. None of that worked. It will fully boot in safe mode. I've tried hdmi, VGA, and DVI.
