I was starting to set up a new desktop. I turned on the computer and found the monitor does not work (I had planned on replacing it soon anyways as it was getting temperamental). I did not take any steps to set up the new computer other than turn it on, other than plugging in mouse, keyboard, the non-working monitor and connecting to internet. I have ordered a new monitor that will be delivered tomorrow. Is it okay for me to turn the computer off until I get the new monitor tomorrow? Thank you.
