so out of nowhere my computer makes noise that ressembles one small piece of metal drilling onto another.
its not really out of nowhere,it happens when I play a game only,and,if I take the side panel off the problem is fixed.
I'm pretty sure that when I close the case I do it decently,so with the screws n'stuff.
I'm kinda wondering if anyone's got an idea what's going on
Sounds like case rattling to me. Typically happens with side panels, so it makes sense. The only time you should seek replacing something is if heatsink/PSU/whatever fans start making grinding noises (worn out bearings).
