Windows bugged after the update

I’ve updated an old pc from windows 7 to 10. After an update that occured a few days ago, when I click the power button, the pc loads, gets into the pin stage. And when I try to login, it does nothing but a short flash that appears as if you’d click f5 in a brower, but really quick.

I’ve no options in the menu, but to shutdown the computer manually from power button. The computer always gets very noisy. As if I’d run a game on max settings and the pc would work at its 100% capability.

How can I reformat/login/do anything? I’ve no way to reach safe mode, nor the windows screen, as I have no options available. Where the power icon appears, it only tells me something about power consumption. Which lets me do nothings.

Faced same thing.

Great article, but it would be nice if you added an example with navigation.
