Turns out the [product|IF188-088|trackpad cable] was causing the issue, after replacing that with a new one everything is working again!

EDIT (1/1/22): Ok so that wasnt the problem. The laptop worked great after that cable was replace, stress tested for hours with zero issues in mouse movement and no issues keyboard wise. I then closed the lid, and put it away for about 36hrs before opening it up again to find everything still working fine. I then went to create a new user account and midway through the issue occurred again. I then managed to crank the fans to 100% to cool the CPU only to find that it wasnt under heavy load nor was it overheating. The next step is to check and swap the mousepad but I am first going to check the keyboard and see if there are any obvious shorts. Will edit this post if I find anything.

EDIT 2 (1/1/22): So as it turns out, one of the connectors to the mousepad is corroded which lead to the erratic behavior of the trackpad and hence the system.

So I will be attempting to clean this connection for now while the new mousepad is on its way. Also good to note: this laptop lives in a rather humid and salty climate (tropical island) so it is possible that a little bit of moisture with a small amount of salt weaseled its way into the laptop causing this corrosion. Phew, what a troubleshooting journey this has been.
