I got an i5 4690k as an upgrade from my old fx 4350. I have been playing games and such but on multiple occasions my game crashes but I still hear audio and both my monitor and TV say input not supported or no video signal. I didn't clean install windows but it has been working fine until now. I reset my pc and removed all files but it still has these problems. I made sure all cables were plugged in properly and my video drivers were up to date. As of right now the my PC crashed, I force shut down and restarted, and now its stuck Working on Updates 30% complete.
