I clicked on software update today and learned that there were updates that needed to be installed. I clicked on update and after some twenty minutes, it's asked to restart to install the updates. When it was done, I got this message on the screen UNABLE TO FIND DRIVER FOR THIS PLATFORM ACPI. YOU NEED TO RESTART YOUR COMPUTER. HOLD DOWN THE POWER BUTTON UNTIL IT TURNS OFF, THEN PRESS THE POWER BUTTON AGAIN.
I did this but it comes back to the same screen.
Help me please.
