My laptop keyboard keeps sending random keystrokes even though I am not typing anything

My issue is my keyboard is pretty much broken, it keeps inputting keys like Delete, TAB, Numlock, windows key, and others. This is super annoying as not only does it get in the way of doing pretty much anything, but also impacts the performance of the laptop as well. For now I have disabled most keys that it presses with a program called MapKeyboard, but that also blocks input from my USB keyboard, and some of the keys I'd like to keep because I need to use them.. like the windows key, TAB and delete. My goal is to get the laptop keyboard to stop all input, essentially disabling it. When previously searching for an answer I came across this : http://ptscr.com/bd8v22 and http://ptscr.com/bd8wxu However when I tried both options(uninstalling the driver and preventing reinstall or installing invalid driver), I was unable to boot the machine, as it would BSOD me every boot, even in safe mode. I was left with no option but to do a fresh windows install. I noticed that the fresh install did not have the keyboard issues, but as soon as Windows Update ran, the issues came back. I have tried uninstalling and reinstalling every possible driver, and I'm quite frankly out of ideas. My laptop is an Acer Aspire V3-772G. Was hoping someone had a solution. All I want to do is block all input from the built-in laptop keyboard without it affecting an USB keyboard.
