Acer Aspire R7-572 touchscreen mouse pointer randomly jumps all over the screen.

Recently started having a problem with the mouse pointer randomly jumping all over the screen. It's gotten so bad that I can't even use the computer at this time because the pointer won't stay in the same place long enough for me to type or select anything. I typically use the laptop in the screen forward configuration so I don't use the touch pad and nothing is touching it. I use the touchscreen about half the time and use an external USB mouse the rest of the time. It makes no difference which method I use or whether the external mouse is connected or not. Really need some help here as my fancy 4-month old laptop is essentially useless at this point.
