Good morning.... I was using my computer, then I saw an Intel card driver update in Windows update. I clicked "install". After that, Windows screen became black and I can only movel the cursor. If I click the power button, the computer screen turns off, but When i click it again, there is the black screen again. Is there some way of switching it off and accessing the bios? (to install Windows again), or to solve this problem?. Thanks in advance for your help, technology is rebelling to me
