My system is slow & displays buffering, I'm considering Reset my PC

I didn't run SFC/DISM as I didn't know what it was and hoped Acer would help resolve the problem.

SFC and DISM are things advisors say when they don't know what else to say.

The System File Checker checks to see whether protected Windows system files are missing or out of date, by comparing them with the versions of the same files included with the copy of Windows that will be used to reset your computer, if necessary (located in your computer's recovery partition.) It is very unusual for these system files to be missing or out of date, and thus running SFC almost never provides a real solution.

Deployment Image Servicing and Maintenance checks to see if the copy of Windows that will be used for a reset (in the recovery partition) is intact, so you would run that if you suspected that the copy of Windows in your recovery partition is somehow damaged.

I'll admit that it can be quite difficult to identify the root cause of a problem at times, so people sometimes just give up and do a reset. That can help solve a problem, but again, only if the problem is caused by Windows. From your description, it seems like you're having a problem with your touchpad. That usually isn't so hard to diagnose.

Start by uninstalling any touchpad utility software that may have been installed to add or modify touchpad features. Then uninstall the touchpad itself (from Device Manager.) Then restart your computer.

When your computer restarts, windows will detect the presence of a touchpad and automatically install the driver that the laptop manufacturer or the touchpad manufacturer provided to Microsoft. If the touchpad works fine after that, you know that the original problem was probably caused by either the touchpad driver or by the accessory touchpad utility software.

If you're still having a problem with the touchpad after all that, then the touchpad may have a physical problem. Unfortunately, this is something that can only be determined by showing the touchpad to a professional technician.

One common issue that touchpads share, unfortunately, is a problem with palm rejection. Palm rejection is the ability of the touchpad to avoid reacting to your palm when it brushes up against the touchpad. This may not be your problem but it's easy enough to check if it is: Many touchpads have software that can alter the touchpad's sensitivity to palm brushes.
