Erratic/Unresponsive Touchpad

Hey.

Ive a Dell Inspiron 5459 and I’ve been facing this problem of erratic cursor since the past week. My OS is windows 10 64 bit.  It started right after I had updated the bios and installed some security updates for windows. The cursor started lagging and malfunctioned so I just started with an external mouse.

However, today when I was just checking the updates and all, I happened to enter the bios and was kinda flabbergasted by the fact that the touchpad was fully functional and smooth inside the bios. This meant one thing: it wasn’t an internal problem, but prolly a driver issue.

I uninstalled the devices under mouse in the device manager and installed new Synaptics driver but that didn’t help. I uninstalled the updates that were recently installed and even downgraded the bios but all in vain. After all this, hoping against hope I decided to format and install a fresh copy of windows. That didn’t help either. Even with a fresh copy of windows, the cursor kept jumping from one point on the screen to another rendering the touchpad useless. It’s been almost an year to this laptop and I’ve never faced this issue before. Any sugggestions and solutions other than ‘install latest drivers, uninstall old drivers’ would be appreciated as I’ve already tried everything and searched a lot on the forums but haven’t found any significant solution.

Help.. please!

And if there's an external mouse connected to the system:
