I am a Windows 10 user. I have Dell Inspiron 15 5000 Series laptop with i5, 8gb ram.
Even when the laptop was new it used to create a lot of noise. After certain point of time I have realized that it is due to high memory consumption. Sometimes the processes consume a lot of memory and disk usage without any perceptible reason. This has become a big issue with the laptop. Most of the time I have chrome open and I have around 10 tabs open, and it starts making too much noise. I have tried killing some of the processes but to no avail. Sometimes it is some Windows process, thus it becomes impossible to kill it.
I would request you please help me solve this menace. Below I have attached some snapshots of the task manager. This is within 5 minutes of rebooting the laptop. Some System was taking too much disk space. Also the RAM usage is 2gb which is quite high. Moreover I would like to disable Cortana which is burden to my system.
