Wow…36 hours….something got screwed up in your render. I’m afraid you’re going to have to shut down your pc. The only thing that will get corrupted would be your rendered file.
To shut down your pc with just the keyboard do this:
Press the Windows key and release…….now press the right arrow key once……..now hit enter.
Is your bios set up to do an instant shut down when you press the start button? If it is, go into your bios at another time, and change it to power off after 4 seconds. I’m sure you have already made up your mind to change the setting to turn off the display……I physically shut down the display if I feel like it sometimes.
