My windows Inspiron 15 laptop constantly gets stuck and boot loops and needs windows reinstalled. How can I stop this ?

Replace the computer parts from other computers. I did that to my Lenovo laptop and broke up my brother's laptop (he wasn't happy but anyway)

if you reinstall windows and it still boot loops then you have some hardware issue.

likely the hard drive is failing.

first thing i would do is replace the hard drive and reinstall windows again.

if that fails then you will have to take it to a repair shop so they can examine it and determine the fault (as it would be almost impossible for me to do it remotely)

also make sure you are doing a "CLEAN" reinstall aka format the drive in the windows setup THEN install windows on that clean drive. Installing it on top of an existing install could cause the same issues to occur. 

You can communicate with a computer technician.

As you said, reinstall windows.

it is crying out for the attention of a technician

If it boots correctly once you can tell Windows to do a Recovery.  See this link.

But if it never boots correctly, Anonymous gave you the right solution with creating a bootable thumb drive.

Run the Windows 10 Media Creation Tool from the Microsoft website on another computer to create a bootable USB thumb drive to reinstall Windows 10.

take it to a computer place and get it fixed
