Hi Rayboto,
Welcome to The PCHF,
You can download the app from
here and install it, it will give you an idea of what temperature your
cpu and possibly the VGA card are running at.
Depending on the
cpu you should really be below about 58'c for the
cpu and anything up to 70'c for the VGA card. If they seem high to you, just post the readings and specs of the pc for us and we'll have a look and advise you.
Take care
