is this the only one having this mouse problem

[Windows Central Question]

is there anyone here who can solve me a cursor problem; the cursor goes down by itself and I can't do anything and this is done because of a hacker who injected a code into my memory or in the bios, the problem persists even if I format my PC and install another Windows and also the problem also persists after a mouse change, I tried to find the suspicious process in order to stop it but still no results,please help me solve this problem?
thank you in advance

Is your cursor jumping to a specific spot on the bottom of your screen or is it moving gradually downward? These can mean very different things from a troubleshooting standpoint.

Does your computer have a touchscreen? Ghost touches can be caused by crud on your display or a hardware problem.

The likelihood of someone hacking your computer in that specific way, and to that dramatic an extent, is extremeley minimal.
