Do computers produce any particulates or anything else harmful when running? Is it OK to leave it on 24/7?

Question

I have a PC in my room. I generally tend to sleep with my door closed and leave the computer on constantly. The room has an approximately 10x10 perimeter and my bed is on the opposite end of the room as is the PC. There is an air conditioning vent in my room, so the air isn't simply just stagnating. The PC is a Dell from 2003 or 2004.

I read somewhere that PCs produce small particulates into the air during operation, that pollute the air. This true? By sleeping with it on, am I unnecessarily having exposure to something that could be damaging to my lungs or - courtesy of the olfactory nerve - my brain as well?

And is there anything else possibly/probably emanating from the PC while it's on?

Thanks.

Answer 1

Every so often I hear or read someone talking about this but no one can come up with a vaild article or documented information.  To me it has become an urban legend.

PC's probably collect more dust in your room than anything else.  I'm sure you keep your room immaculately clean without a speck of dust or dirt anywhere.  Opening your computer therefore won't find any dust or dirt either.

I am sure you are safe from this particular problem.

Answer 2

Nope.  Just dust that gets clogged up in there eventuall gets blown out.

I've slept with mine on in my room EVERY night in a room smaller than yours for about 10 years at least.

Im Okay ....as far as i know ?

PC's was designed to be running 24/7

Answer 4

No, but it wastes electricity. You should turn off when not using.
