IMPORTANT: You have also to consider that the issue can happen for HARDWARE problems. In some case the PCI of the graphic card was not plugged properly, in other cases the alimentation cable was not anymore plugged correctly, or double alimentation was missing.
In the worst cases the Graphic Card was broken or some component was not working properly.
We also want to advise that in some cases all the procedures above did not work, and a fresh format of the PC as been the only solution to solve the problem.
