Why is My Trackpad Acting Erratically?

Hello everyone,

I have a ThinkPad T530 that I got from an auction a few days ago. When I started using the laptop after installing an SSD and setting up Windows with drivers, my cursor sometimes does unwanted actions while using the built-in trackpad. For example, the cursor sometimes goes up and down while trying to move right or left. Another example is when the cursor scrolls randomly without the two-finger gesture. Sometimes, it jumps from one place to another for some reason. I have once disconnected and reconnected the trackpad cable, and the issue happens less frequently, but it still sometimes happens. Is there a solution for these weird trackpad issues I am having?

Thanks.
