What happens to my computer if i leave it on for a week?

Slow, High af electric bill, really hot, and not suggested, I was stupid and would never turn mine off it got super low to the point of web browser games going slow.

Not much will probably happen, maybe it will get a little slower.

Nothing. Just keep it well ventilated and you shouldn't have a problem.

Not much, it will slowly degrade hardware faster and it may get a little hotter or slower than usual. PCs don't use much electric when idle, so I personally leave mine on.

Nothing should happen. Although if you dont use proper ventilation, it may over heat and shut off. Other than that, it is fine.

It would blow up!
Just kidding, mine has been on for 3 months straight so far. Very slow!

nothing really i leave my pc on sometimes and its still working fine so

i dont make sleep my computer like 1 week so i think you can leave it for sure only if you dont have a virus :D

You'll use tons of electric for no reason, and it won't do your computer any good mate

I would usually keep my laptop and desktop on for weeks, on desktop I would just turn off the display never had any issues
