I was using my pc to play tf2 the other day and mid game it shutdown, now it will turn on but my monitor, which is a lg tv will not receive a video signal from it. I have a 4770k, r9 270, hero vi, 2 hdd, ssd, DVD drive, and 8 gigs of ram plugged in currently. I have tried used different outputs on the card, switching pcie slots, using on board graphics all with no video output, I can hear the pc turn on and stay on, fans spinning, mouse keyboard, gpu fans etc the weird thing is the audio lighting on the mono does not light up. Any ideas?
