Each time I start my computer, when the desktop is loading, the computer restarts, but if I switch to a TTY by pressing Ctrl+Alt+F1, it doesn't restart.
I have reinstalled Ubuntu 16.04 already, but the problem persists. I don't think it's a hardware issue because Windows works just fine.
What can I do to fix this?
Try Ubuntu without installing
from your install DVD/USB get all the way to the desktop without restarting your computer? – Chai T. Rex Jan 21 '18 at 09:56
