Lines and dots have been apearing on my acer e5

Solution
Soo you're saying that fans are making similar noise to rattling? Like they are hitting something?
But if the laptop is used and release date is over 3-4 years ago I suggest you to take it to repair shop to replace thermal paste atleast and see if that fixes it, or do the both fans and thermal paste.
That usually means either;
A. GPU is going bad
B. The monitor went bad

I would try to connect laptop to the external monitor if possible, if not i would send it for repair if its still under warranty.

How old is the laptop?
When did it start to happen the "lines" issue?
