My friend had a very long shutdown session, so he plugged off the PC for it's turn off. After that, when PC is turn on, there no image on screen. If he connect VGA to integrated video, image is on screen. He was delete AMD drivers using AMD clean utility, reboot PC, and download AMD drivers for his videocard. But the drivers are not installing, it's shows error 182 (device not detected or something like that); He then connect VGA to external videocard (R7 350) and repeat installing driver by keyboard (because no image on screen), after hearing the sound, he connect VGA to integrated graphics and see same error.
What can you advise to solve his problem
