My cursor constantly bounces around in the corner

Hello, first post here. This problem is driving me so berserk that I had to create an account just to ask about it.

So as soon as I get to the lock screen, my cursor starts spazzing out in the lower-left corner of my screen with a weird pointer, it looks sort of like a four-point star; it zips around in a 1x1/2 inch area. Usually, it stops after about 10 minutes, but recently it started doing it perpetually, except only on certain sites. For example, on Google Docs, it goes absolutely crazy and I can only control it for seconds at a time, so I have to click really fast, but on acolytefight.io (which by the way is a really cool 2D spellcasting arena battle game, you should really try it) it works fine. At least my cursor knows what's important!

Still, it makes me quite literally scream at my computer. I have tried deleting, reinstalling and updating devices and drivers for the touchpad and nonexistent mouse (I rarely use my USB mouse, but a mouse still shows up in the list of devices), disabling the touchpad with FnF9, and disabling enhanced pointer precision, which worked for a while then failed.

PLEASE HELP. I NEED TO GRIND MINECRAFT MINIGAME WINS GET WORK DONE AND THIS IS A HUGE IMPEDIMENT. I HAVE TO HAVE THIS RESOLVED.

No idea if this applies, but I use a second monitor with my laptop lid closed. My pointer went nuts and I discovered the lid interfered with the touchpad. I put a some sticky notes on the touchpad and the problem corrected.

On a laptop you can disable the touchpad (by using a switch or a Fn+Fx key).

As I said in the original post, I have tried this and it had no effect. Also, I am usually in a situation where I cannot use my USB mouse (such as being in the car or on the couch). Thanks anyway though.

Thanks, but I only use my own laptop's monitor.

If you have exhausted all options and just have to get it working, then a Reset may be the way to go. Make sure you have backed up your user files to external media, although theoretically they will be untouched. You will have to reinstall your applications.

Hello...? I still need help with this!
