My Inspiron 15 5000 series i7 7th gen runs painfully slow and the fan starts running making a noise even when I am not running an application that isn't demanding, for eg. the Chrome browser. The boot up is extremely slow (takes a couple of minutes until clicking on an icon actually launches an application such as the Chrome browser or the search bar). Applications like MATLAB and Altium really makes the system cry (the sound's way too much and I'm guessing the fan isn't supposed to sound like that).
It's been a year since I bought the laptop and this has been there right from the beginning. Following are the details of the service tag. I already ran the online diagnostics and everything seems to be fine as per the test results although things really are far from being fine.
Please help me in fixing this.
