Windows 10: logging onto desk top computer

I have Windows 10 and am stuck on the administrator log in screen. I have pushed the windows key and r and no run window comes up. I have tried every password for Administrator and can't log on to my desk top computer. I have restarted the computer and nothing changes. How do I change the user from Administrator if the run box does not appear?

Yes, it probably will (when it's on even at idle) if you are talking about a desktop computer. Laptops on the other hand produce less heat but are also more susceptible to heat.

 

Computer Ventilation and Desk

On Saturday, I am getting an Antique Roll Top Desk for my Computer Room. I will be taking the old desk and will be putting it in my room, since I need more desk space.

As you all know, a Roll Top Desk has a top that opens and closes. If I put my tower and monitor on this desk, and close the top, will it cause ventilation issues for the computer? I will only be closing the top when the computer is turned off.

Any help would be appreciated!

P.S. I know this question is a little odd to ask.
