My hp 7 A6 vision AMD doesn't start. I was copying files on to a drive an suddenly a blue print appears saying the pc has to config certain certains. After that it tried to restart buy the screen did not display anything. I manually pressed the power button to turn it off and pressed again to start it was still the same thing but the fun keeps ruuning very fast and the pcc heats up more and more. I changed the screen to a new one and i see some line strips at times when i try to start it the screen is still black. I also connected it to an external monitor but still see black screen. What should i do?
