Last night my pc work 100%, I Installed telegram for windows and in the midnight the download of the Critical Update was installed in my Desktop, I restart my computer and when turned on after the bios I get a Black Screen, isn't my fist time: see my old post on reddit about the black screen:

Problem with a 'Black Windows' in Windows 10 Pro

I lost again everything that I installed because I recovery the system via a image backup. I'm sick of that black screen and lost every time my installed software's and documents, the problem appear after of install "Telegram" (I don't know) and when Windows download and installed in my system the Critical Update...

Thanks in advance
