I install a game of the 5 hours so it takes 3:26 AM so it would be 9: oo tomorrow would be finished what would happen if I leave it open 5 hours? Honest answer please
PCs are made to run for several hours at a time, nothing happens. Just put it in a place where it is not too warm and let it run, then nothing will happen.
I left it on the concrete
As long as he is not on carpet or something, everything is fine.
I have not done that anyway he is beautiful on the concrete and does his work thank you for your quick response good night
At least nothing bad happens.
However, what happens is that he goes into sleep mode because you are no longer active on the PC; that you should disable.
Otherwise nothing happens
When the download is done, your PC gets hacked and it goes out. No, fun side by side. You can set on Steam I believe that the PC to download end goes out. So nothing is going to happen, it's like if you were constantly watching netflix, it's not going to be broken.
