If I've updated software etc, I click on the apple and choose restart, it seems to be heading that way and goes black etc, then I just hear the clicking noise from the tower expected with a restart, but continually, about every 5 seconds, and the screen stays black. I eventually give up and hold down the power button until it turns off then I switch it on again and it runs like normal.
