Galaxy Book Flex α’s cursor is working not well!

Hi!
I have Galaxy Book Flex α and I liked it but unluckily, for the previous 2 3 weeks, Cursor is working not well though I have updated the cursor driver, Sometimes on the upper portion of the screen auto click occurs, I have reinstalled the windows, tested on new power plugs but it is not working. It mostly happens when I work on a site of my client with Nulled wp-rocket installed in them, and when I start working on it, my laptop becomes very hot and loaded, and after a few minutes cursor becomes hang and auto clicks start appearing until I restart my laptop.
Anyone can tell me what is the problem here.
