During the day when I'm not using my PC I put it into sleep mode. During the night I shut it off. Would it make a big difference if I shut it off during the day when I'm not using it? (In terms of PC life)
Honestly from a technician stand point it dont matter, if you leave it on 24x7 you only waste your power which isnt much, you have a higher chane of you hdd sticking when you do turn it off, and as for overheating it well only kill if its not in a open area where air can flow.
but no days computers are also on suppose to keep you happy for no more hten 4 years if that.
I leave my laptop on and i reboot it once a week, its non stop being used even when im not by it, its still doing stuff, i have yet noticed any issues with it since i have gotten it 6 months ago.
And my computers where only shut down when i moved recently other then that they stay on all the time.
