I think my desktop's fan is on it's last leg. It sounds like it's stressed or something when I turn the computer on.
Why do you think it's stressed.
It makes a weird noise. I don't really know anything about computers, though.
Well, technology can get pretty complicated. It's fine to be confused by it. Hopefully you can find someone to fix it so it works right.
I hate computers. They are complicated and noisy.
They certainly can be complicated, which is why there's no shame in calling a professional to take a look at the problem. They'll be able to see what's wrong right away.
